I have 2811 routers at two different site connecting with MPLS.
I would like to use the Frame Relay as a back up. Can I use WIC 2T on these routers? Is WIC 2T compatible for 2811? The router is version 12.4. Is there any special configurations for this set up?
Yes you can use the WIC-2T in the 2811. As you probably do not "see" any MPLS configuration, and are only an user of carrier service, it will be just a traditional routing configuration.
