EIGRP load balancing over T1 Point to Point Circuits

[jackremboldt]

3 questions. The third is the most important.

1. I have 2 circuits connected to the same 2811 router (pairs), how can I configure EIGRP to load balance the traffic?

2. I have 1 Circuit in each of 2 seperate 2811 Router (pairs) How can I configure these to balance the traffic?

3. I have 2 Circuits in each of 2 pairs of 2811 routers, how can I load balance accrossed all 4 circuits.

Thanks, Jack

This should be achieved easily by configuring all links with the same bandwidth. EIGRP will then automatically load-balance between identical circuits. I think that you can use eigrp variance to account for the difference caused by the local LAN hops:

Hope this helps you out.
