Attached is a FDDI configuration diagram which I'm trying to get a
verification on. The core of the question is "Do you have to have
a ring or dual ring in a FDDI configuration."
The config below is simply two concentrators connected in a cascaded
fashion using SMF. There is no dual ring. A competitor has said that
they don't think this is valid. Two questions:
a) Do you have to have a dual-ring
b) have I configured the concentrators below correctly
(ie; the B-port of concentrator #1 plugged into
an M-port of concentrator #2?)

> a) Do you have to have a dual-ring No. a physical dual ring is not required in FDDI. For all practical purposes, the dual ring is located inside Concentrator #2. > b) have I configured the concentrators below correctly > (ie; the B-port of concentrator #1 plugged into > an M-port of concentrator #2?) It looks good to me. | |||||
