In the Test topology i have three Compute node's and
Have a single VM instance running on each compute node.
Extra routes is configured for the Two compute node's pointing to the two VM's IP
I had initiated ping from VM-3 on CN-3 to the extra route IP and
when i bring down the tunnel interface on which traffic is getting forwarded it doesn't switch to the alternate path.
