Multiple paths on non-switchports on 3750

Unanswered Question
Dec 18th, 2007

I have a 3750 that connects to a 2821 and a 2811. The 2800s connect to our MPLS WAN and use eigrp. How can I get the 3750 to use both paths to the MPLS? It does not seem to use both at the moment. We seem to get congested on the 2821 often while the 2811 seems to have no traffic.

This is our “main” site all our other sites access resources here via T1 connections.

I have this problem too.

You can configure routed ports in the 3750.


interface fx/x

description 2821

no switchport

ip address

interface fx/x

description 2811

no switchport

ip address

then use a dynamic routing protocol or stating routing for balancing both links.


Keep in mind, you are affecting outbound traffic from the 3750 toward the MPLS routers, you aren't affecting inbound traffic on the MPLS routers' WAN links.

That would be a separate configuration and/or requirements.
