See "Site to Site Redundancy" here..

http://www.cisco.com/en/US/docs/security/pix/pix63/configuration/guide/ipsecint.html#wp1045462

"You can define multiple peers by using crypto maps to allow for redundancy. This configuration is also most useful for site-to-site VPNs. If one peer fails, there will still be a protected path. The peer that packets are actually sent to is determined by the last peer that the PIX Firewall heard from (received either traffic or a negotiation request from) for a given data flow. If the attempt fails with the first peer, IKE tries the next peer on the crypto map list."

crypto map newmap 10 set peer 1.1.1.1

crypto map newmap 10 set peer 2.2.2.2

isakmp key ******** address 1.1.1.1 netmask 255.255.255.255

isakmp key ******** address 2.2.2.2 netmask 255.255.255.255

Please rate if it helps.

In this case, does I need a configure a two static outside route to remote LAN for load balance ?
