I have an issue where I have a DMVPN set up with EIGRP. I have a secondary tunnel configured with one of the spokes in the primary tunnel is the hub of the secondary tunnel. Here are the configurations I have:
Now what happens is that when I shut down the tunnel0 interface on RouterA, everything fails over to the tunnel1 interfaces. When I bring back up the tunnel0 on RouterA, everything keeps using the tunnel1 interfaces. When I check show ip nhrp detail and sh ip eigrp topology/neighbours, its as if the other tunnel interface doesn't exist anymore.
How can I get this to fail back over properly. I thought of something just now that isn't configured the way I have it in my diagram. Router A is configured as a spoke in the backup tunnels. Do you think that this could have been the source of my problem? I can't test this until tomorrow morning as the maintenance window is gone but I'd appreciate any ideas until then
