You're getting a race condition because you're injecting the tunnel's ip address into your control plane routing. Your tunnel protocol is using your routing to transfer payload from one end to another. However when you use the ip address of the tunnel and injecting it into your routing protocol, your router will now think that the best way to get from tunnel endpoint A to endpoint B is to send all packets "control packets included" into endpoint A, this will be 1 hop away. This will cause recursiving routing.
To fix this, remove the tunnel network address from your EIGRP routing process. As a rule of thumb for implementing any GRE tunnel and putting an ip address on them, NEVER ADVERTISE YOUR TUNNEL ADDRESS INTO ANY ROUTING PROTOCOL THAT YOUR ROUTER IS USING TO TALK TO EACH OTHER". Hope this helps. -Doan Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=74208&t=74035 -------------------------------------------------- **Please support GroupStudy by purchasing from the GroupStudy Store: http://shop.groupstudy.com FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html
