VPN Tunnel will not complete
Posted on 2012-03-28
I am wondering if anyone else runs into issues like this. Phase 1 at the remote site(Cisco 881 series router) will complete, but then comes back to the main firewall(clustered 5520s) and Phase 2 does not complete. In the past I have rebooted our 5520 cluster and that seems to fix it everytime, but i have over 140 remote sites and when I do that, it usually takes a long time for all tunnels to rebuild. Are there certain commands that can be used in CLI on the 5520 cluster that will clear any caching issues?
