DMVPN - 2600 crash

[gauthier]

Hi,

I'm testing DMVPN using 2620 and 2621 routers.

I tested them with version 12.2.15T2 and the 12.3(1).

One of the 2600 is configured as Spoke . It does works for a while. But from time to time, the router will crash and reload. With both version tested.

I have 32M of Flash and 64M of DRAM.

Here is the output when it crash:

--------------------

00:16:53: %NHRP-3-PAKREPLY: Receive Resolution Reply packet with error - insufficient resources(5)

The other router, configured as Spoke or Hub doesn<t seem to get this problem.

Any Ideas why is it crashing ?

Thanks !

I did some further testing.

The problem seems to be related to Redundant Hubs.

If I only have one Hub ans many spoke, it works fine.

If I have two Hub, one for redundancy, then I get the error message when I try to ping one of the hub, which crash the Spoke router itself.

Where can I find a good configurations (hubs and spokes) of DMVPN using a two Hubs for redundancy ? I may have configuration errors that provoke this crash.

Thanks for all your help.

Francois.
