F5 and Cisco ASR SLA

Hi,   I have a scenerio where we have two F5s (Active / Standby) mesh connected to Cisco ASR 9000 routers with /31 subnets for the mesh connecitivty.   How can we implement SLA on the Cisco ASR...

Why not use a single subnet for your mesh which the floating IP is part of? Especially if you use MAC Masquerade the failover will be seemless and again, there will be no need for IPSLA (but you will need HSRP). Then use the 1.1.1.1/29 just for your Virtual Servers (assuming that's its primary purpose)?

 

 

Without a common network between the four devices (as you've found) you are making life very difficult for yourself.

 

 

I wonder how the return traffic routing works at present too, if an ASR fails?
