Ok, here is the latest. I guess I do have time for this...
BVI1 BVI1

-----R5----------------------R1----------------------R7--t5/3
s0 s1 to0 t5/0
R1 is doing SR/TLB and IRB, R5 is IRB still and R7 is not doing any
bridging. In this setup nothing works at all. When I ping from R1 to R7,
R7 gets encap failed trying to reply. When I ping from R5 to R1 nothing
happens, I haven't spent a lot time on that.
When I ping from R5 to R1, the BVI's mac shows up in R1s bridge table, and
R7s mac is also in the bridge table.
Looks like two problems, R7 can't get back to R1 and R1 isn't dealing with
the IPX traffic from R5 for some reason.

I'm sorry I am at work and had to go to a meeting, and I was writing quickly
without analyzing your information very accurately. I didn't catch that good
point you had- no ethernet involved.
It would seem like in your scenario you would have to use source-route
bridging on the Token-Ring. I believe it's an either or thing with SRT and
SR/TLB.
I would think you would have to configure a ring-group, reconfigure the
Token-Ring interface to use source-route bridging, and point the next hop
ring to the ring-group, then add the SR/TLB stuff?
Have you come up with anything else?
