Hope you all are doing great.
I have requirement where my old IP range (SUBNET) is fully exhausted. Now we got new range of ip (Subnet).
So can we configure two subnet (one for old default route (already exist) and one for new subnet) in F5 for same partition. Doing so will have an impact on existing default route ?
No, if Auto Last Hop is still enable on you F5 BIG-IP.
Auto Last Hop is a setting that allows the BIG-IP system to track the source MAC address of incoming connections and return traffic from pools to the source MAC address, regardless of the routing table.
No need, please read K article and you see that Auto Last Hop feature allows packets to be routed without interrogating routing table.

If everything seems OK on BIG-IP configuration, you can do a tcpdump on the F5 BIG-IP to identify root cause of the routing issue.
Hey RAQS ,
Did that work? Did you do any additional steps? I am also looking for a similar solution, your feedback would help me implement better.
Do you have any article/doc that sums up all the steps to do so?
Thanks in advance.
