Hi,
If I understand correctly, the way to use multiple VRRP addresses on same subnet is to simply add the new virtual address on the same VRRP interface.
It seems to work, but doing so disrupts VRRP operation, as you now have a peer mismatch until the peer is configured accordingly. I can't really have disruptions like that, and if I do it on the active peer first, I lose connection to it, due to it affecting the WAN interface. I can of course make sure to do it on the backup peer first, but even then there's some disruption. Is there any way to do it gracefully?
