parallel T-1 Link

[RJGlasener]

We are in the process of replacing 3com netbuilder II routers with a cisco 3620 and 2621. Presently the two routers are connected through two physical T-1's and they are setup as one logical path with load sharing. So my question is how to configure the cisco units to utilized both of the T-1 interfaces.

Router 2 should look like this.
