Setting EIGRP Hold Timer Longer Than GRE Recursive Routing Loop Timer

I'm tired of adjacency rediscovery because GRE downs/ups an interface to force EIGRP to discover routes again after EIGRP mistankenly accepts a route to a distance tunnel loopback via the tunnel. I want to increase the EIGRP hold timers to greater than that to stop GRE from forcing my network from converging so many times a day. How long does it take for GRE to shut down/up an interface? I will then increase the hold timer to greater than that interval.

Why don't you block tunnel destination whic it is learning from tunnel itself? You can use distribute-list or distance commands to stop learning destination routes in EIGRP.

How about just not adding the network to EIGRP command?

So if the remote loopback IP is x.x.x.x and local is y.y.y.y

Why not just configure the local EIGRP without "y.y.y.y"?
