Always remember this.. maybe do what I did and print it in large letters
and paste it on the top of my monitor:
3920 RING NUMBERS ARE IN [HEX]
forget that and you are sure to mess it up. I am almost betting my life
the ring numbers will NOT be from 1 to 9 :-)))
All other numbers are not that important as they are not relevant to the
outside world such as the routers connected to the rings. When a router
looks at the ring, it only sees the ring number. It does not see bridge
numbers inside the the 3920. Unless of course they are fully
participating in Source Route Bridging, in which case they will see the
RIF populated with the path up to this point and yes, all bridges and
rings should be in there.
Hope this helps
