Problem on Failover when VS is not same subnet as the SelfIP

Hi All,

 

I have inquiry regarding problem i encountered last week, i have VS which has different subnet with my SelfIP. It is working on my primary but when we failover, traffic still goes to the primary(standby), what might be the problem?

 

Thanks...

    Thanks Vitaliy, we conduct testing using mac-masquerading but still doesn't work.

    Could be stale/old ARP cache entries. After configuring mac-masquerading did you see the ARP table update itself on the upstream router to the new MAC address? Just a thought.
