EIGRP and PRI lines problem

[zubairjalal]

I have having a PRI card in 7206 VXR router. My 13 branches are terminating on PRI and all of them are end devices(stub). I am running eigrp on all of them. I am getting ping drops say after every 30 seconds and if i use static routes, everything seems to work ok.

Have you changed any timer settings in Eigrp. If u have done so this klind of problem may arise. Try debug eigrp events and u will find more information

Are there any missing / flapping neighbors on any of the routers?

show ip eigrp neighbors

Check for large discrepencies in uptime, SRTT set to 0, or a large number for RTO. Any of these things could indicate EIGRP having trouble communicating with its neighbors. This can be cuased by any number of things (Broken Multicast routing, access list blocking eigrp etc).

If you do find a problem with eigrp try this:
