I'm having trouble getting SR/TLB to work...Here's my config:
RtrA--------------RtrB---------------HostA
ether token
RtrA:
interface fastethernet 0/0
ip address 10.1.1.2 255.255.255.0
RtrB:
no ip routing
source-bridge ring-group 3
source-bridge transparent 3 4 11 1
interface ethernet 0/0
bridge-group 1
interface tokenring 0/0
source-bridge spanning 1
source-bridge 2 12 3
ring-speed 16
bridge 1 protocol ieee
HostA has an IP address of 10.1.1.1 255.255.255.0
My understanding is that the above configuration should cause traffic on the
Token RIng network to be bridged to ring 3 (virtual-ring), which then
bridges it to pseudo-ring 4 (actually ethernet bridge-group 1). However,
pings do not seem to be able to cross the bridge.
When I "debug source bridge" on RtrB and try to ping HostA from RtrA, this
is the output (I also included the output of "show source-bridge"):

It looks like the RtrB recognizes that Ring 3 (the virtual-ring) is attached
to the actual token ring (2) via bridge 12 and attached to the pseudo-ring
(4) via bridge 11, which is what I anticipated. It also seems to be
forwarding the pings from RtrA to ring 3, but not from ring 3 to ring 2:
bn: 12 rn: 2 local ma: 400b.5d1b.f681 TokenRing0/0 fwd: 0
bn: 11 rn: 4 locvrt ma: 400b.5d1b.f601 Bridge-group 1 fwd: 5
I can't figure out what the "duplicate ring violation" is referring to,
because I made sure that I used different ring numbers for the actual token
ring, the pseudo-ring, and the virtual-ring, but I'm guessing this is
somehow related to my lack of connectivity.
Can anyone shed some light on this situation for me?
Thanks,
Jack
