As far as I understand it, The TrBrf bridge number and router bridge
number as specified in 'source-bridge x x x' are not the same so do
not need the same values. The bridge number on the router is different
than that on the switch but the ring number is the same.

Try making the VLAN ID and the Bridge number different.
i.e Create a BRF with an VLAN ID of 5o and a bridge number of 50, that
should do the trick.

Subject: Cat 3920 configuration question
I have a scenario with 2 token ring interfaces off two separate routers
and a 3920.
Router A - Ring 50 Router B - Ring 50 Both connected to port 1
& 2 on 3920
Using default 3920 config I can ping between each router to the other
router. After configuration I am unable to ping between routers.
I configured 3920 by creating a CrBRF with id of VLAN50 and bridge
number of 50
Then configured CrCRF 1 and CrCRF 2 with CrBRF VLAN50 as the parent.
Also assigned port 1 to CrCRF 1 and port 2 to CrCRF 2.
Left everything else default - including ring number set to auto, etc.
On the routers I only configured an IP address and ring speed on the
token ring int's.
What else is needed? Do I need to change the switch from SRB to SRT
since no workstations to create RIF's? Do I need to change the ring
setting on the switch from auto to the actual ring number of 50? Do I
need to configure sour bridge ring group on the token ring interface?
As a side question - I read on CCO that the 3920 CRF and BRF numbers are
in hex format. So if I have bridge 50 (decimal) shouldn't I configure
the switch with a value of 0x32 (yet on the router I would assign it
decimal 50?) Also same for ring numbers such that ring 50 decimal =
switch 0x32 ring number and router 50 decimal)...
Thanks in advance,
Ian
