VPN 3k tunnels die if concentrator loses network connectivity
I have a VPN 3030 Concentrator running 4.0.5 (It will be upgraded to 4.1 this weekend) and several 501/506e PIXes running 6.3.4 in a hub-n-spoke config. The concentrator is connected to a switch, which connects to our Internet gateway router. If the switch is rebooted or the Concentrator is unplugged from the switch for a few seconds, all IPSec/LAN-to-LAN 3DES-168 tunnels from our remote PIXs enter a zombie state; the tunnels show as up on the concentrator, but no traffic flows. If I "logout" the remote IPsec tunnels, the tunnels won't come back up. I have to reboot the Concentrator, and then the tunnels come up again. Is this a bug or a feature?
