Okay, I need you to be more specific. You would like to route one E1 card in one router to an E1 in another router, or the same router? You would like the destination to be the ethernet interface?

I Agree with mikecr.

Can you be more specific, about what you want to do?

If both of your E1's are in the same router, I'm going to assume that you have an ethernet card installed also. To get incoming traffic to go to your internal network you need to first turn on IP routing and second put in a static route to your internal network. It would look similiar to this.

Command to turn on routing

ip routing

Next, if your internal network is lets say, and the next hop from the router is a switch with a vlan IP address of and your routers ethernet IP is, you would add the following route:

ip route

You can only route (Layer 3) between E1 interface to a Ethernet interface, no bridging (Layer 2)

Here's my typical setup at work for E1 or T1
-----E1 Line-----CSU/DSU------Router------Ethernet

you'd better use two router E1->Eth and Eth->E1
