hi all, i would like to get some guidance on the VPN failover design, just like we do in BGP where the neighbours form neighbour relationship with each others loopback addresses, can we do the same in site to site VPN ? like both of the peers form vpn on some GLOBAL ip ( like ip on loopback or ethernet interface ) so that if 1 of the link goes down vpn is not disrupted..

Any idea ??

My design is very simple. I have 2 routers RA and RB connected via 2 serial links. now in normal cases of site to site vpn i will establish peering between RA and RB on any of these serial links ip addresses. but i want to peer between some GLOBAL ip on both of these routers to ensure transparent redundancy !!

i hope this clarifies
