Our inbound internet pipe (t1) is constantly being maxed out during the daytime load. Our ISP has reccommendated upgrading to a 3Mb CEF bundle. Although it costs more then just adding an add'l T1, we have a 2621XM.
Does CEF require both serial interfaces to terminate on the same router?
My understanding is that CEF provides load balancing but I'm not sure which route to take, add a T1 from our current provider (or a new one) or purchase the 3Mb bundle. and whether either solution requires adding a router or is a wic sufficient?
