I am looking to add a new connection between a Cisco 2851 and a Cisco 3745. Currently there are two T1 connections between them for a internal 192.168.5.0 network but I would like to add a ethernet connection to give a larger pipe for when transfering large files via that network. Can I just add the ethernet to the multigroup and shut the ethernet connection down when not needed(to limit it to t1 speeds) or is there some other way of doing this?
I have added the configs and a rough diagram below. Currently the shutdown ethernet connections are unused and would be reconfigured.
Thank You.
