Sorry, I have to respectfully disagree, I'm pretty certain you can have all
your bridges with the same number.
If you think about it, the rings don't make the decisions, the bridges do.
A bridge makes its decision based on a "next-ring" number, it does not care
that the next bridge down the line is also a "one" or that a duplicate
bridge number "one" would grab the wrong frame. A bridge can only connect
two rings, and would only forward a frame that has the correct next ring
number. What I said about all the bridges can be "one" is not based on
such logic, it's based on experience with SRB in a SNA environment several
years ago.
When I used to configure PS2-Model-30's (PC-XT processor that's Intel 8080
for those of you who played with PCs before the 286) as a SRB, I saw no
reason NOT to make them all one. I didn't change my attitude when doing it
with cisco routers configured for SRB, basically bridge numbers are
irrelevant, you can set them to anything except zero, when it doesn't work
it's usually because you got a duplicate ring number.

Bridge numbers only need to be unique for the ring that you are on. A single
ring can't connect to two bridges with the number of one, or it will not
know the correct path. You can have two bridges numbered one in a network,
just not connected to the same ring.

The problem iis that you want mutliple(redunancy) path between two rings and
you need more
than one bridges, so within thw two rings, the bridge number may need to be
different.

The way I had it explained to me was that the bridge number does not have to
be unique because it will always fall between two rings, which are always
unique.

~Bridge number is not necessary to be unique if connected in
~serial. It may need to configure
~to a different number if it is in parallel.
~
~Asume two parrallel bridges between ring_1 and ring_2
~
~for eg (ring_1)-\Bridge_1/-(ring_2)-\bridge_1/-(ring_3)

~Dear all,
~
~In SRB, does the bridge numbers have to be unique? For example, is
~0810.0041.0051.0060 valid?
~
~TIA
