Hi, Is it possible to make a 2513 with 2501 and a 2502 router? I know 2 2501 can be put together to make a frame relay switch using tunnelling, using the ethernet interface to tunnel. What about using the serial interface in each of the 2501 and 2502 to tunnel, allowing it to be a router with a ethernet and token ring interface? If this is possible, then are there any limitation with this method. Can it still do RSRB and SR/TLB like the 2513?
