I was wondering if anyone runs gre tunnels over carp. We have an OpenBSD router that does ipsec over gre tunnels with remote location routers in order to pass voip traffic.
Routing is done with ospf on top of gre. I'd like to add sasyncd in the mix and a 2nd router for higher availability. Will gre over carp work? I'd prefer to use the carped IP in the tunnel and not the real IP of each server, so eventually 1 tunnel (active) per remote router. How will this work when I demote master and go via backup? Thanks, G
