What happens when you plug two token ring routers into the same MAU
and assign different ring numbers to the segment is not fun, you will get an
error messages on each router telling you of the two different ring numbers.
The first router/bridge active on a segment sets the ring number, all other
devices must match this ring number. The second router may not insert onto
the ring, I just do not remember, some bridges will accept the already
assigned ring number (remember the IBM 8229?)

IPX can't beacon!!! &;-) I don't know how we managed to move up to the
network layer anyway. The question was "Can you configure multiple rings on
a single MAU?"
The answer is no. A MAU is a physical-layer relay. It's like an Ethernet
hub. Two rings requires at least a bridge or switch.
To be honest, I don't know what would actually happen if you plugged two
2500s into the same MAU and assigned two different ring numbers. I can't
think of anything in the Token Ring protocols that addresses this problem.
But I do know that it would be illogical, illegal, and downright ugly, kind
of like what's going on in Florida. &;-)
