CirrostratusF5 VS Conflict with citrix configuration through our migration.
MVPYup, as stated earlier... VIP will still respond to ARP and you may need to clear cache. I presume you are migrating a few VIPs at one time and not a single "big bang" migration. I would selectively disable ARP on all VIPs and then bring up as you migrate.
Also, how are you handling the network routes? Did you create new Self IP addresses for the network, or are you using the same IP addresses for the network as on Citrix? If you are migrating a few at a time and need both networks up to both Citrix and F5, you may have issues. You will eventually need to move a route to the F5 self IPs. However, if you are only moving a few VIPs at a time, you may need to temporarily put in more specific /32 routes for the VIPs individually as you move services from VIP on Citrix to VIP on F5.
Some more considerations 😉
IredaHellowhisperer, thank you so much for your reply.
Yes, I am migrating a few at a time and need both networks up to both Citrix and F5. I used new IPs for the self and floating but from the same subnet of citrix, Ex: citrix self IP 10.10.20.2, F5 self IP: 10.10.20.5.
Also I added specific routes /32 for backend server on F5. Regarding FW policy I allow connection from outside to "VIP /32".
But I did not disable ARP or ICMP. if I need both networks up to both Citrix and F5 to test F5 before the migration, Can I disable ARP and ICMP for spesific VIP not for all?
