We have two parallel metro Ethernet links into the same VLAN from a critical site, but our provider doesn't support link aggregation/Etherchannel (and they're different speeds anyway), so we only have manual failover so far.
Cisco Performance Routing apparently can re-route if a link is degraded or down. Is there anything comparable (or can CPR be adapted) for our Layer 2 Metro-E world? Or is there a better way? (Note: each of our dozen sites has an L3 connection into the shared metro VLAN. We run RIPv2 on a mix of switches and routers.) We like the idea of failing over if the main link is degraded, since that's happened already due to provider hardware problems.
Thanks for your thoughts!
