dmvpn timeout

[stephen.stack]

Hi Guys,

I wonder can any of you help me?

I have a central site with 6 DMVPN tunnels from it. 2 of the tunnnels seem to lose connection sporadically.

How can i troubleshoot this. Is there a timeout setting i can adjust. is there an issue with DMVPN tunnels.

Thanks

Stephen

If you use the Dynamic Creation for Spoke-to-Spoke Tunnels benefit of this feature, you must use IKE Certificates or wildcard preshared keys for Internet Security Association Key Management Protocol (ISAKMP) authentication.

Thanks For the reply. I have implemented Pre-shared Keys. I think if you have any troubleshooting tips ie debugs and Show's then i may be able to tell the customer that the issue lies with the DSL lines.

Thanks in Advance.
