Bulk-Create Secondary DNS Zones in F5 Distributed Cloud (via API)
If you’ve ever had to onboard dozens (or hundreds) of domains as secondary DNS zones in F5 Distributed Cloud (XC), you know the drill: click through the console, fill in the domain, add the primary server IP, save, repeat. It works - but it doesn’t scale. I ran into exactly this situation recently and figured a quick shell script would save me (and maybe you) a lot of clicking. What it does The script reads a simple text file - one domain per line, comma-separated with its primary DNS server IPs - and creates the corresponding secondary DNS zones via the F5 XC API. The input file looks like this: example.com, 10.0.0.1, 10.0.0.2 example.org, 192.168.1.1 internal.example.net, 172.16.0.1, 172.16.0.2, 172.16.0.3 Run the script, and it works through the list one by one: $ ./create_secondary_dns.sh Starting secondary DNS zone creation... Tenant : acmecorp --- [line 1] Creating secondary zone: example.com (primaries: 10.0.0.1 10.0.0.2) [line 1] OK - example.com created (HTTP 200) [line 2] Creating secondary zone: example.org (primaries: 192.168.1.1) [line 2] OK - example.org created (HTTP 200) --- Done. Success: 2, Failed: 0, Total lines: 2 That’s it. No Python, no Terraform, no extra frameworks - just bash, curl, and jq. TSIG support If your primary DNS servers require TSIG authentication for zone transfers, the script handles that too. Set the TSIG key name, algorithm, and secret in the configuration block, and the script will encrypt the secret locally using vesctl (the F5 XC CLI) before sending it to the API. If vesctl isn’t installed yet, the script downloads it automatically. If you don’t need TSIG, just leave the TSIG variables empty and the script skips that part entirely. Getting started 1. Clone the repo and navigate to the tool: git clone https://github.com/de1chk1nd/resources-and-tools.git cd resources-and-tools/tools/dns-secondary 2. Create your domain list: cp domains.txt.example domains.txt 3. Open the script and fill in your tenant name and API token: vi create_secondary_dns.sh 4. Run it: chmod +x create_secondary_dns.sh ./create_secondary_dns.sh The full README in the repository covers all configuration options, dependencies, and common error messages. What happens when something goes wrong? The script validates every line before hitting the API - domain names are checked for valid DNS characters, IP addresses are checked for valid IPv4 format. If a line is malformed, it’s skipped with a clear message and the script moves on to the next one. If a zone already exists in XC, the API returns a 409 and the script logs it as a failure but keeps going. At the end, you get a summary: how many succeeded, how many failed.

That said, it works well for my use cases and I hope it’s useful for yours too.

I always want to automate as many tasks as possible. I have already a pipeline to import ASM policy templates. Today I had the demand to update this base policies. Simply overwriting the template with the import tasks does not work. I got the error message "The policy template ax-f5-waf-jump-start-template already exists.". Ok, I need an overwrite tasks. Searching around does not provide me a solution, not even a solution that does not work. Simply nothing, my google-foo have deserted me. Quick chat with an AI, gives me a solution that was hallucinated. The AI answer would be funny if it weren't so sad. I had no hope that AI could solve this problem for me and it was confirmed, again. I was configuring Linux systems before the internet was widely available. Let's dig us in the internals of the F5 REST API implementation and solve the problem on my own. I took a valid payload and removed a required parameter, "name" in this case. The error response changes, this is always a good signal in this stage of experimenting. The error response was "Failed Required Fields: Must have at least 1 of (title, name, policyTemplate)". There is also a valid field named "policyTemplate". My first thought: This could be a reference for an existing template to update. I added the "policyTemplate" parameter and assigned it an existing template id. The error message has changed again. It now throws "Can't use string (\"ox91NUGR6mFXBDG4FnQSpQ\") as a HASH ref while \"strict refs\" in use at /usr/local/share/perl5/F5/ASMConfig/Entity/Base.pm line 888.". An perl error that is readable and the perl file is in plain text available. Looking at the file at line 888: The Perl code looks for an "id" field as property of the "policyTemplate" parameter. Changing the payload again and added the id property. And wow that was easy, it works and the template was updated. Final the payload for people who do not want to do reverse engineering. Update POST following payload to /mgmt/tm/asm/tasks/import-policy-template to update an ASM policy template: { "filename": "<username>~<filename>", "policyTemplate": { "id": "ox91NUGR6mFXBDG4FnQSpQ" } } Create POST following payload /mgmt/tm/asm/tasks/import-policy-template to create an ASM policy template: { "name": "<name>", "filename": "<username>~<filename>" } Hint: You must upload the template before to /var/config/rest/downloads/<username>~<filename>". Conclusion Documentation is sometimes overrated if you can read Perl. Missed I the API documentation for this endpoint and it was just a exercise for me?Simplifying and Securing Network Segmentation with F5 Distributed Cloud and Nutanix Flow
Introduction Enterprises often separate environments—such as development and production—to improve efficiency, reduce risk, and maintain compliance. A critical enabler of this separation is network segmentation, which isolates networks into smaller, secured segments—strengthening security, optimizing performance, and supporting regulatory standards. In this article, we explore the integration between Nutanix Flow and F5 Distributed Cloud, showcasing how F5 and Nutanix collaborate to simplify and secure network segmentation across diverse environments—on-premises, remote, and hybrid multicloud. Integration Overview At the heart of this integration is the capability to deploy a F5 Distributed Cloud Customer Edge (CE) inside a Nutanix Flow VPC, establish BGP peering with the Nutanix Flow BGP Gateway, and inject CE-advertised BGP routes into the VPC routing table. This architecture provides full control over application delivery and security within the VPC. It enables selective advertisement of HTTP load balancers (LBs) or VIPs to designated VPCs, ensuring secure and efficient connectivity. By leveraging F5 Distributed Cloud to segment and extend networks to remote location—whether on-premises or in the public cloud—combined with Nutanix Flow for microsegmentation within VPCs, enterprises achieve comprehensive end-to-end security. This approach enforces a consistent security posture while reducing complexity across diverse infrastructures. In our previous article (click here) , we explored application delivery and security. Here, we focus on network segmentation and how this integration simplifies connectivity across environments. Demo Walkthrough The demo consists of two parts: Extending a local network segment from a Nutanix Flow VPC to a remote site using F5 Distributed Cloud. Applying microsegmentation within the network segment using Nutanix Flow Security Next-Gen. San Jose (SJ) serves as our local site, and the demo environment dev3 is a Nutanix Flow VPC with an F5 Distributed Cloud Customer Edge (CE) deployed inside: *Note: The SJ CE is named jy-nutanix-overlay-dev3 in the F5 Distributed Cloud Console and xc-ce-dev3 in the Nutanix Prism Central. On the F5 Distributed Cloud Console, we created a network segment named jy-nutanix-sjc-nyc-segment and we assigned it specifically to the subnet 192.170.84.0/24: eBGP peering is ESTABLISHED between the CE and the Nutanix Flow BGP Gateway in this segment: At the remote site in NYC, a CE named jy-nutanix-nyc is deployed with a local subnet of 192.168.60.0/24: To extend jy-nutanix-sjc-nyc-segment from SJ to NYC, simply assign the segment jy-nutanix-sjc-nyc-segment to the NYC CE local subnet 192.168.60.0/24 in the F5 Distributed Cloud Console: Effortlessly and in no time, the segment jy-nutanix-sjc-nyc-segment is now extended across environments from SJ to NYC: Checking the CE routing table, we can see that the local routes originated from the CEs are being exchanged among them: At the local site SJ, the SJ CE jy-nutanix-overlay-dev3 advertises the remote route originating from the NYC CE jy-nutanix-nyc to the Nutanix Flow BGP Gateway via BGP, and installs the route in the dev3 routing table: SJ VMs can now reach NYC VMs and vice versa, while continuing to use their Nutanix Flow VPC logical router as the default gateway: To enforce granular security within the segment, Nutanix Flow Security Next-Gen provides microsegmentation. Together, F5 Distributed Cloud and Nutanix Flow Security Next-Gen deliver a cohesive solution: F5 Distributed cloud seamlessly extends network segments across environments, while Nutanix Flow Security Next-Gen ensures fine-grained security controls within those segments: Our demo extends a network segment between two data centers, but the same approach can also be applied between on-premises and public cloud environments—delivering flexibility across hybrid multicloud environments. Conclusion F5 Distributed Cloud simplifies network segmentation across hybrid and multi-cloud environments, making it both secure and effortless. By seamlessly extending network segments across any environment, F5 removes the complexity traditionally associated with connecting diverse infrastructures. Combined with Nutanix Flow Security Next-Gen for microsegmentation within each segment, this integration delivers end-to-end protection and consistent policy enforcement. Together, F5 and Nutanix help enterprises reduce operational overhead, maintain compliance, and strengthen security—while enabling agility and scalability across all environments. This integration is coming soon in CY2026. If you’re interested in early access, please contact your F5 representative.

Equinix and F5 Distributed Cloud Services: Business Partner Application Exchanges
As organizations adopt hybrid and multicloud architectures, one of the challenges they face is how they can securely connect their partners to specific applications while maintaining control over cost and limiting complexity. Unfortunately, traditional private connectivity models tend to struggle with complex setups, slow on-boarding, and rigid policies that make it hard to adapt to changing business needs. F5 Distributed Cloud Services on Equinix Network Edge provides a solution that makes partner connectivity process easier, enhances security with integrated WAF and API protection, and enables consistent policy enforcement across hybrid and multicloud environments. This integration allows businesses to modernize their connectivity strategies, ensuring faster access to applications while maintaining robust security and compliance. Key Benefits The benefits of using Distributed Cloud Services with Equinix Network Edge include: • Seamless Delivery: Deploy apps close to partners for faster access. • API & App Security: Protect data with integrated security features. • Hybrid Cloud Support: Enforce consistent policies in multi-cloud setups. • Compliance Readiness: Meet data protection regulations with built-in security features. • Proven Integration: F5 + Equinix connectivity is optimized for performance and security. Before: Traditional Private Connectivity Challenges Many organizations still rely on traditional private connectivity models that are complex, rigid, and difficult to scale. In a traditional architecture using Equinix, setting up infrastructure is complex and time-consuming. For every connection, an engineer must manually configure circuits through Equinix Fabric, set up BGP routing, apply load balancing, and define firewall rules. These steps are repeated for each partner or application, which adds a lot of overhead and slows down the onboarding process. Each DMZ is managed separately with its own set of WAFs, routers, firewalls, and load balancers. This makes the environment harder to maintain and scale. If something changes, such as moving an app to a different region or giving a new partner access, it often requires redoing the configuration from scratch. This rigid approach limits how fast a business can respond to new needs. Manual setups also increase the risk of mistakes. Missing or misconfigured firewall rules can accidentally expose sensitive applications, creating security and compliance risks. Overall, this traditional model is slow, inflexible, and difficult to manage as environments grow and change. After: F5 Distributed Cloud Services with Equinix Deploying F5 Distributed Cloud Customer Edge (CE) software on Equinix Network Edge addresses these pain points with a modern, simplified model, enabling the creation of secure business partner app exchanges. By integrating Distributed Cloud Services with Equinix, connecting partners to internal applications is faster and simpler. Instead of manually configuring each connection, Distributed Cloud Services automates the process through a centralized management console. Deploying a CE is straightforward and can be done in minutes. From the Distributed Cloud Console, open "Multi-Cloud Network Connect" and create a "Secure Mesh Site" where you can select Equinix as a Provider. Next, open the Equinix Console and deploy the CE image. This can be done through the Equinix Marketplace, where you can select the F5 Distributed Cloud Services and deploy it to your desired location. A CE can replace the need for multiple components like routers, firewalls, and load balancers. It handles BGP routing, traffic inspection through a built-in WAF, and load balancing. All of this is managed through a single web interface. In this case, the CE connects directly to the Arcadia application in the customer’s data center using at least two IPsec tunnels. BGP peering is quickly established with partner environments, allowing dynamic route exchange without manual setup of static routes. Adding a new partner is as simple as configuring another BGP session and applying the correct policy from the central Distributed Cloud Console. Instead of opening up large network subnets, security is enforced at Layer 7, and this app-aware connectivity is inherently zero trust. Each partner only sees and connects to the exact application they’re supposed to, without accessing anything else. Policies are reusable and consistent, so they can be applied across multiple partners with no duplication. The built-in observability gives real-time visibility into traffic and security events. DevOps, NetOps, and SecOps teams can monitor everything from the Distributed Cloud Console, reducing troubleshooting time and improving incident response. This setup avoids the delays and complexity of traditional connectivity methods, while making the entire process more secure and easier to operate. Simplified Partner Onboarding with Segments The integration of F5 and Equinix allows for simplified partner onboarding using Network Segments. This approach enables organizations to create logical groupings of partners, each with its own set of access rules and policies, all managed centrally. With Distributed Cloud Services and Equinix, onboarding multiple partners is fast, secure, and easy to manage. Instead of creating separate configurations for each partner, a single centralized service policy is used to control access. Different partner groups can be assigned to segments with specific rules, which are all managed from the Distributed Cloud Console. This means one unified policy can control access across many Network Segments, reducing complexity and speeding up the onboarding process. To configure a Segment, you can simply attach an interface to a CE and assign it to a specific segment. Each segment can have its own set of policies, such as which applications are accessible, what security measures are in place, and how traffic is routed. Each partner tier gets access only to the applications allowed by the policy. In this example, Gold partners might get access to more services than Silver partners. Security policies are enforced at Layer 7, so partners interact only with the allowed applications. There is no low-level network access and no direct IP-level reachability. WAF, load balancing, and API protection are also controlled centrally, ensuring consistent security for all partners. BGP routing through Equinix Fabric makes it simple to connect multiple partner networks quickly, with minimal configuration steps. This approach scales much better than traditional setups and keeps the environment organized, secure, and transparent. Scalable and Secure Connectivity F5 Distributed Cloud Services makes it simple to expand application connectivity and security across multiple regions using Equinix Network Edge. CE nodes can be quickly deployed at any Equinix location from the Equinix Marketplace. This allows teams to extend app delivery closer to end users and partners, reducing latency and improving performance without building new infrastructure from scratch. Distributed Cloud Services allows you to organize your CE nodes into a "Virtual Site". This Virtual Site can span multiple Equinix locations, enabling you to manage all your CE nodes as a single entity. When you need to add a new region, you can deploy a new CE node in that location and all configurations are automatically applied from the associated Virtual Site. Once a new CE is deployed, existing application and security policies can be automatically replicated to the new site. This standardized approach ensures that all regions follow the same configurations for routing, load balancing, WAF protection, and Layer 7 access control. Policies for different partner tiers are centrally managed and applied consistently across all locations. Built-in observability gives full visibility into traffic flows, segment performance, and app access from every site - all from the Distributed Cloud Console. Operations teams can monitor and troubleshoot with a unified view, without needing to log into each region separately. This centralized control greatly reduces operational overhead and allows the business to scale out quickly while maintaining security and compliance. Service Policy Management When scaling out to multiple regions, centralized management of service policies becomes crucial. Distributed Cloud Services allows you to define service policies that can be applied across all CE nodes in a Virtual Site. This means you can create a single policy that governs how applications are accessed, secured, and monitored, regardless of where they are deployed. For example, you can define a service policy that adds a specific HTTP header to all incoming requests for a particular segment. This can be useful for tracking, logging, or enforcing security measures. Another example is setting up a policy that rate-limits API calls from partners to prevent abuse. This policy can be applied across all CE nodes in the Virtual Site, ensuring that all partners are subject to the same rate limits without needing to configure each node individually. The policy works on the L7 level, meaning it passes only HTTP traffic and blocks any non-HTTP traffic. This ensures that only legitimate web requests are processed, enhancing security and reducing the risk of attacks. Distributed Cloud Services provides different types of dashboards to monitor the performance and security of your applications across all regions. This allows you to monitor security incidents, such as WAF alerts or API abuse, from a single dashboard. The Distributed Cloud Console provides detailed logs with information about each request, including the source IP, HTTP method, response status, and any applied policies. If a request is blocked by a WAF or security policy, the logs will show the reason for the block, making it easier to troubleshoot issues and maintain compliance. The centralized management of service policies and observability features in Distributed Cloud Services allows organizations to save costs and time when managing their hybrid and multi-cloud environments. By applying consistent policies across all regions, businesses can reduce the need for manual configurations and minimize the risk of misconfigurations. This not only enhances security but also simplifies operations, allowing teams to focus on delivering value rather than managing complex network setups. Offload Services to Equinix Network Edge For organizations that require edge compute capabilities, Distributed Cloud Services provides a Virtual Kubernetes Cluster (vK8s) that can be deployed on Equinix Network Edge in combination with F5 Distributed Cloud Regional Edge (RE) nodes. This solution allows you to run containerized applications in a distributed manner, close to your partners and end users to reduce latency. For example, you can deploy frontend services closer to your partners while your backend services can remain in your data center or in a cloud provider. The more services you move to the edge, the more you can benefit from reduced latency and improved performance. You can use vK8s like a regular Kubernetes cluster, deploying applications, managing resources, and scaling as needed. The F5 Distributed Cloud Console provides a CLI and web interface to manage your vK8s clusters, making it easy to deploy and manage applications across multiple regions.

Show or List F5 XC Routes in the Web
Hi F5ers, After more than two years working with F5 XC, I have decided to explore a functionality to show the host associated with each route "I have requested this functionality to F5, but it´s in design." For anyone who has deployed XC and has created routes into the load balancers, they may have encountered the fact that the routes don't have any description or relevant information, and in the case that they have to find a specific route, it could be almost impossible in an incident, or it will take a lot of time to navigate the menu. So, what I propose as an alternative solution, meanwhile, is F5 solving the request? I have designed a JavaScript that can be integrated into a bookmark "easy way", and if you copy the entire JSON configuration of the load balancer, it will show you in a console over the main XC web page the specific routes and their position in the Routes Menu. The steps to deploy it are: Create a new bookmark and copy the next encoded JavaScript in the URL New Bookmark javascript:(async()=>{const H=h=>{if(!h)return'';const i=h.invert_match?%27NOT %27:%27%27;const n=(h.name||%27%27)+%27%27;if(n.toLowerCase()===%27host%27){if(h.regex)return`${i}Host Regex: ${h.regex}`;if(h.exact)return`${i}Host: ${h.exact}`;if(h.match_value)return`${i}Host: ${h.match_value}`;if(h.value)return`${i}Host: ${h.value}`;if(Array.isArray(h.values)&&h.values.length)return`${i}Host in [${h.values.join(%27 | %27)}]`;return`${i}Host Header Present`}if(h.regex)return`${i}Header Regex: ${n} ~ ${h.regex}`;if(h.exact)return`${i}Header: ${n} = ${h.exact}`;if(h.match_value)return`${i}Header: ${n} = ${h.match_value}`;if(h.value)return`${i}Header: ${n} = ${h.value}`;if(Array.isArray(h.values)&&h.values.length)return`${i}Header: ${n} in [${h.values.join(%27 | %27)}]`;return`${i}Header: ${n} (present)`},S=t=>{try{let s=t.replace(/^\uFEFF/,%27%27).replace(/\u200B/g,%27%27);s=s.replace(/\/\*[^]*?\*\//g,%27%27);s=s.replace(/(^|[^:])\/\/.*$/gm,%27$1%27);s=s.replace(/,\s*([}\]])/g,%27$1%27);return s}catch{return t}},J=t=>{if(!t)return null;try{return JSON.parse(t)}catch{try{return JSON.parse(S(t))}catch{return null}}},G=()=>{try{return(getSelection()?.toString()||%27%27).trim()}catch{return%27%27}},D=()=>{const o=[];document.querySelectorAll(%27pre,code,textarea,div%27).forEach(el=>{const t=(el.innerText||el.textContent||%27%27).trim();if(t&&t.includes(%27"spec"%27)&&t.includes(%27"routes"%27)&&t.includes(%27"metadata"%27))o.push(t)});return o},P=a=>{for(const r of a){let t=r,i=t.indexOf(%27{%27),j=t.lastIndexOf(%27}%27);if(i>=0&&j>i)t=t.slice(i,j+1);const x=J(t);if(x?.spec?.routes)return x}return null},M=()=>{try{if(window.monaco?.editor?.getModels){for(const m of window.monaco.editor.getModels()){const txt=m.getValue?.();const j=J(txt);if(j?.spec?.routes)return j}}}catch{}return null},Q=onOk=>{const host=document.createElement(%27div%27),shadow=host.attachShadow({mode:%27open%27}),ov=document.createElement(%27div%27);ov.style.cssText=%27position:fixed;inset:0;z-index:1000000;background:rgba(0,0,0,.55);display:flex;align-items:center;justify-content:center;outline:none;%27;ov.tabIndex=0;const box=document.createElement(%27div%27);box.style.cssText=%27width:min(960px,92vw);height:min(76vh,720px);background:#111;color:#eee;border:1px solid #444;border-radius:10px;box-shadow:0 8px 24px rgba(0,0,0,.35);display:flex;flex-direction:column';const head=document.createElement('div');head.style.cssText='padding:10px 12px;border-bottom:1px solid #333;font:600 14px system-ui';head.textContent='Pega o carga el JSON del HTTP LB (vista JSON)';const bar=document.createElement('div');bar.style.cssText='display:flex;gap:8px;align-items:center;padding:8px 12px;border-bottom:1px solid #333';const btnRead=document.createElement('button');btnRead.textContent='📋 Leer portapapeles';btnRead.title='Requiere permiso del navegador';btnRead.style.cssText='background:#2b2b2b;color:#ddd;border:1px solid #444;border-radius:6px;padding:6px 10px;cursor:pointer';btnRead.onclick=async()=>{try{const txt=await navigator.clipboard.readText();ta.value=txt;ta.focus()}catch{alert('No se pudo leer del portapapeles.

Copy or upload the JSON code of the load balancer In the XC web menu, execute the bookmark and copy the JSON code, and then click on validate and show. It shows you the specific routes and number position for each route, giving the possibility to find the required route easily and quickly. Hope it works for anyone who has the same problem as me.
