Can anyone tell me how to provide redundant connectivity with multiple T1 WAN connections and fiber trunks? Lets say we have building A, B, and C. Building A houses a 3662 and a 4006 that serve as the VLAN domain server. The 3662 has at lover 20 point to point T1's. One of the buildings connected via T1 is building B. Building B has a T1 to building C, and C to A. Anyway, everything was great until I added the 1000Base-LX fromm building A's 4006 to a 2950 in building B. I connected the 2950 building B's 1720, put building B's E0 port on the same subnet as the 3662. Everthing takes the fiber trunk now. If I shut down the GBIC on the 2950 I lose connectivity. Question is how can I route from the 2950 to the 1720 w/ the GBIC shutdown?
