L2L VPN timing out, even after keepalives set...

Subject: L2L VPN timing out, even after keepalives set...
Date: Thu, 20 Sep 2007 16:51:31 -0500
Hello list,

I have a cisco 506e and 515e that are endpoints in an L2L VPN. The VPN works
great, except one issue. The VPN seems to drop whenever the rekey time limit
is reached, even though I have keepalives set for each SA.

The default rekey time is 8 hours, and sometimes this falls into the middle
of the day and you can imagine how that might urk some people. I've used the
"isakmp keepalive 20" command on both firewalls, but it doesn't make a
difference. 

Any help and suggestions are greatly appreciated...

Dan
