F5 Load Balancing and Cisco Routing

Hey all, In our current setup we have 2 BIG-IP 2000s in HA pair. Both have uplinks to the Internet. Currently the F5s are doing all of the internal routing for our network. Since our needs have ...

You are correct. Basically the issue is that the floating IPs (Default Gateway for VLANS on F5s) will conflict with the ASR's VLAN DFGW of 172.19.xyz.1. I don't want to change the .1 on the ASR side since all our servers point to .1 So the current setup is:

F5-1 (Active) ------> Internet 1 [VLANS 110-111, 120-123, 130,140,141,160] ------> Trunk to Core Switch

F5-2 (Passive) -----> Internet 2 [VLANS 110-111, 120-123, 130,140,141,160] -----> Trunk To Core Switch

Future Setup:

F5-1 (Active) ------> Internet 1 ------> Trunk to ASR 1 (All VLANS reside on ASRS) F5-2 (Passive) ------> Internet 2 ------> Trunk to ASR 2 (All VLANS reside on ASRS)

Is there a clean way of doing this without messing around with the nodes/pools on the F5s?
