Technically, if you have 2 paths to the destination in your routing table, you'll roll over to the second path with almost no downtime. This is going to depend on both ends though having two paths. You can see if you have at least 2 paths to the remote site with a "show ip route". If you only see one path in there, you can look at your eigrp topology table to see if it sees 2 paths. "show ip eigrp topology" At a minimum, you'd need two paths listed to the same subnet in the topology table for a quick failover. If you don't and you failover, the router will need to query neighbors for a successor and if it doesn't find one, then you'll blackhole traffic because there will be no route at all.
