Hello Arun, Yes it is possible. Assuming that the ethernet bridges are doing 802.1 transparent bridging, it could transit multiple intervening bridges. This should have an effect on transmission propagation delays and nothing else. An 802.1 bridge will not alter the ethernet frames that are in transit (unless the frame is bad according to 802.3, in this case it will be dropped). -Ben On Wed, 20 Feb 2002, Arun M.
