Background first:I am at the tail end of deploying a dual cloud DMVPN similar to the following:http://www.cisco.com/warp/public/105/dmvpn_05.gifalthough my 2 hub routers are at disparate locations.My main data center has an MLPPP connection with 8 T1...
I have some past experience with point to point GRE tunnels (100+ locations with a single hub). This is my first time with DMVPN and Im having some odd issues.Topology:2 Hub locations (3825's)6-12mbps (can be scaled up if needed)114 Remote locations...
I am using DMVPN (tunnel mode GRE multipoint) with 120 or so tunnels on a DS3 (remote site T1's). Termination point is a 3825 running at an average of 15% CPU. I've had it up just over a year now and couldn't be happier. I can deploy a new site wit...
Problem Solved. Unfortunately its something that will probably not satisfy others with similar issues.Long winded explanation:Our 2 main hub locations are running through AT&T managed routers (how I let them talk me into that I don't know).In the co...

The remote routers have 2 tunnels, the odd thing is only one of the tunnels has the problem. I would think it is a scaling problem if BOTH tunnels lost their adjacencies.The remote just gives a holding time expired message:059186: *May 12 07:33:43.8...
I've been so busy I haven't tried working on it much. I did try to bring up a separate EIGRP session and run it exclusively between the backup site and the remote router but ran into the same problem.Im going to open a TAC case.
