I have a 20mb DS3 that's getting installed at a remote branch. We have a 20mb DS3 circuit here as well, and we don't want the remote branch being able to suck down all of our bandwidth.
I can shape the traffic on the outside interface for the remote branch, but if I shaped it from 20mb to 3mb, would that take a major hit on the routers cpu? It's a DR site, and the only time we want them to be able to use 20mb is if we had to go over there because of a DR situation. The router is a 3745, and there are about 100 users at this location.
