I have two ASA both are remote sites which currently has a leased line. Static router are placed on the ASA to route traffic via the leased line. I want to be able to introduce a VPN failover connection between the sites and run EIGRP over the VPN tunnel.
I know its possible to run EIGRP using a GRE tunnel on a router, but I can't seem to find any information in terms of running EIGRP (GRE tunnel) with only ASA as the only Cisco device on each remote site.
you can use OSPF over VPN using unicast instead of multicast. If OSPF is running you can have multiple paths to a destination and the traffic will use both paths when active or you can tell which path is the desired. If one goes down it will use the one active.
