All,
I have a Cisco 2821 configured to bond two T1's from one provider with CEF. This network connects, in turn, to Gig0/0 to my production firewall. All of this works fine. However, another T1 has been brought in for another purpose. I want to route any traffic from Gig0/1 to this new T1 and from the new T1 to Gig0/1. I know this can be done with something like EIGRP, but will is mess up my current routing? I'm sure if I make a specific route for this ethernet interface, I'll have to do the same for the other, no? Anybody have an example floating around that I could see?
