Tunnel stays down after isakmp phase 1 renegotiation - ??

Unanswered Question
Mar 10th, 2010


Is there a way to disable the Isakmp phase I negotiation?

The Ospf  tunnel goes down when the phase I renegotiates after 24 hours.

Nothing in the logs except Tunnel going down, Ospf losing neighbor.

Ipsec is up but Tunnel stays down !!

Any ideas?



I have this problem too.

Phase 1 SA shouldn't affect your ospf neighbor; as long as your ipsec sa is up, the ospf neighbor should stay.

What are the devices on both sides? Is it default timer for isakmp lifetime? what timer is ospf using?
