We're not using PPP authentication on the links. So it must be using the endpoint discriminator.

Well, we considered using EIGRP load balancing, but I can't find verification that EIGRP will load balance IPX traffic, which is needed. We run both IP and IPX. As far as CEF goes, the routers at the remote ends of our bundles are uslaly 2500s, so I don't think CEF is an option. We are using MLP to load balance over multiple T1s. The virtual-templates seems to be working just fine, so I guess my questions here are more academic in nature. Thanks for your input! Mike W.
