5 TopicsNeed to Re-ip the VIPs, Self-ips and mgmt IPs
Hi Experts, I have following requirement: I have to re-ip some VIPs which are currently on 4.x.x.x/24 network to 10.x.x.x/24. Can I reconfigure the old VIPs with new IPs I have self-ip(static and floating) in External and Internal Vlans , which are also need to be re-ip to 10.x.x.x/24 segment. Can I change the IPs or do I need to create new self-Ips for external and internal VLans. I have a default route on my LTMs pointing to L3 switch : list /net route all-properties net route /Common/Gateway { description none gw 4.x.x.1 mtu 0 network default partition Common } Do I need to delete this default route and create a new route which will be a L3 SVI in 10.x.x.1 Can I keep the old default route and create a new for 10.x.x.1 , will that work. Can I use forwarding VIP. Also if I remove the old self-ips and the old default G/w , will it create any outage.. I am planning to do the configuration changes on Standby device first and then make it as Active and once tested successfully, I will sync the devices. Kindly assist.. It will be great help and much appreciate it !133Views0likes2CommentsIs floating self-ip necessary under one-arm HA deployment?
Hi all, Under in-line ( two-armed ) HA deployment, the floating self-ip is necessary to process traffic, like to be pool member's default gw. But , under the one-armed HA deployment, I use SNAT AutoMap to ensure the return traffic. And the HTTP(s) application session can be reset / re-establish on another F5 device when failover occur. That is to say I don't need to enable connection mirror on virtual server and I don't need the same self-ip / mac for SANT AutoMap selection. In this case, is floating self-ip still needed?564Views0likes1CommentVIP IS MARKED GREEN BUT CANNOT BE PINGED, POOL MEMBERS HAVE CONNECTIVITY FROM F5
Hello,Is there any possibility, where a configured VIP on an LTM can be unreachable, even though marked GREEN. The Pool members however can be reached directly. Is there an explanation for this,and how can this be resolved. The Self-Ip is configured correctly,and other VIP in the same VLAN are reachable188Views0likes1CommentDoes the Big-IP use its management IP address to query the internet for F5 updates?
I'm seeing my F5 try to query the internet to check for updates after I manually pressed "Check Now" from the update check page. It's currently trying to reach out to the internet from its Self-IP, not the management address. Should the F5 being using its Self-IP by default to query that update server out in the internet or should it be using its management IP address? I ask because I currently have a static default route on the F5 that says if you're going to 0.0.0.0, take your default gateway at 10.251.12.1 (the default gateway for the Self-IP). Is this why it's trying to source the request from that address or would it be doing it by default anyway even if I didn't have that default route set?Solved445Views0likes5Comments
