Load balancing IPSEC traffic

[CHRISTINE BERNS]

Is it possible to set up a site to site VPN between two routers and somehow automatically load balance the VPN traffic over multiple T1 lines connecting the two routers? In other words, if one has two equal cost paths to the remote site and one applies the same crypto map to both interfaces, will some encrypted traffic be sent over each one of the links.

Yes, you can load balance the traffic. Just use a loopback interface and apply the crypto map to the loopback interface as well as the serial interfaces. As long as the routing is setup correctly for equal paths you will be all set.
