GTM - DNS delegation according to manual
im looking at delegated zones for GTM, i first looked at 11.2.1 document BIG-IP Global Traffic Manager: Implementations section Delegating DNS Traffic to Wide IPs. then at Creating a delegated zone on a local DNS server it says: In order for BIG-IP GTM to manage the web applications of store.siterequest.com and checkout.siterequest.com, you must create a delegated zone on the DNS server that manages www.wip.siterequest.com. Perform the following steps on the selected DNS server. 1) Create an address record (A record) that defines the domain name and IP address of each BIG-IP GTM in your network. 2) Create a nameserver record (NS record) that defines the delegated zone for which BIG-IP GTM is responsible. 3) Create canonical name records (CNAME records) to forward requests for store.siterequest.com and checkout.siterequest.com to the wide IPs store.siterequest.com and checkout.siterequest.com, respectively. to me it seems this approach can't work. anyone with experience with this agree? from some testing i think there are two alternatives: 1) create some sort of intermediate NS which you point CNAMES to, so create the gtm.siterequest.com zone and then create CNAMES in the siterequest.com zone store.siterequest.com --> store.gtm.siterequest.com checkout.siterequest.com --> checkout.gtm.siterequest.com 2) just create the NS records for the store.siterequest.com and checkout.siterequest.com with the name server being the the GTM and then you can use whatever you want before store / checkout.siterequest.com, i.e. www.store.siterequest.com but the description from the manual is just wrong in my opinion. i checked a couple of other versions manuals and so far only the 11.0 makes sense, it uses the intermediate zone approach. the rest want to use the second approach (i guess) but keep mentioning these CNAMES which don't do make sense in that approach.696Views0likes2CommentsZone delegation to GTM/DNS Question
We have a customer whose DNS zone is hosted at an ISP. Say the zone is Customer.com The customer has many hosted websites at his own premises and he want to migrate to GTM, but not all websites at once, just one after the other. I was wondering how I would be able to do that without changing at all once, I was hoping someone might have doen that before but I have a suggestion, it would be great if I get feedback for that. I was thinking that maybe we ask the ISP to create a zone called, internal.customer.com and for each website the customer has, say for example eservices.customer.com, we would ask the ISP to create a CNAME record that translates eservices.customer.com to eservices.internal.customer.com And then we would delegate the zone (internal.customer.com) to the GTM, and for each new A record we want to move we would do the same. Then on GTM we would create a zone called internal.customer.com and a wide ip A type called "eservices.internal.customer.com" that has an Alias of "eservices.customer.com" I am not very familiar with DNS/GTM setups but this is my suggested approach, is there an easier way for a smoother migration and easier rollback? Thanks in advance.Solved464Views0likes3Comments
