does anyone know if its possible to have two routers at a remote branch (one primary, the other backup with HSRP) connecting back via IPsec VPN's to a Head office PIX 515E with ver6.3.5.

When I lab the scenario, the pix seems to get confused in fail-over scenarios and I need to clear the vpns (clear crypto sa) on the routers to make the vpns come back up. thoughts?

the pix has the two routers as peers under the one crypto map:

access-list vpn400 permit ip

crypto ipsec transform-set avalanche esp-des esp-md5-hmac

crypto map forsberg 21 ipsec-isakmp

crypto map forsberg 21 match address vpn400

crypto map forsberg 21 set peer

crypto map forsberg 21 set peer

crypto map forsberg 21 set transform-set avalanche

crypto map forsberg 21 set security-association lifetime seconds 3600 kilobytes 4608000

crypto map forsberg interface outside


sakmp enable outside

isakmp key ******** address netmask

isakmp key ******** address netmask

on routers you should enable RRI

on PIX and routers try to enable "crypto isakmp keepalive"
