PIX to PIX IPSEC VPN IKE Phase 2 problem

Hi !

Just my 2 cents :-)

IKE phase 1 (ISAKMP) is using a default lifetime of 86400 seconds. (3600 
in the scenario)
IKE phase 2 (IPSec) is using 28800 seconds default. (and the scenario is 
using the default ....
.... the default for PIX ver. 6.3 anyhow)

I wonder if you can have the IKE control channel (IKE SA) torn down before 
the 2 unidirectional data channels (the IPSec SA's). Try to set the 
lifetime lower on the PIX'es. e.g. :
Branch PIX 501
crypto map VPN 100 set security-association lifetime seconds 1800
