Can anyone suggest me the config how i can acheive this.
"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."
