Hi EAX. I have configured OSPF between F5s and the Junipers. And configured ip forwarding virtuals. Active/Standby work just fine. I am now trying to reach a host configured in the load balancer vlan. Pings work fine but the traceroutes are a bit icky. In the traceroute o/p, the load balancer hop is constantly flapping between the two interfaces of the active unit, and at times there is a loop between the interfaces of the active unit. It finally does reach the destination, but curious as to what is causing this behavior. Did you encounter this behavior when your HA pair was setup with the ASRs? Thanks.
