Currently in our network we use dot1Q trunks to forward end-user/customer VLANs from Site A to Site B to provide them virtual point-to-point circuits between data centers without the overhead of some type of VPN tunnel.
However if one of our backhauls between data centers fails, we would desire these VLAN's to forward via an alternative backhaul path (All of our data centers have at least 2 exits to other datacenters in our network, and are meshed via OSPF/BGP) It seems like there are a lot of different approaches to provide some level of self-healing/redundancy to these layer2 services we offer, I am interested in advice on which would be most straightforward to implement on top of our existing layer3 network. Perhaps implementing Rapid-PVST is the simplest approach, but I'd be interested in some best-practices knowledge here.. Thanks!
