IPsec VPN High Availability with HSRP
This is a feature of that support VPN with HSRP, redundant IPsec peer for VPN network.Some notes for this topic:
-HSRP only support on Ethernet and some L2 ATM, such as LANE...
-With the test on 12.4, there're difference in time to recover the VPN connection b/w two peers. Recover time from secondary router ( previously standby) is faster. Preempt delay time is not in effect.




Two or more interfaces are configured in IEEE bridge-group and routing to other subnets via Bridge Virtual Interface (BVI). The transparent firewall only apply to traffic crossing the bridge, not for traffic that leaves the bridge-group via BVI.
