Sure, no problem. The working config is quite a bit simpler than what I was
trying before. R2 is handling the translation, and here are the relevant
portions of its config:
no ip routing
!
interface Serial0
no ip address
no ip route-cache
no ip mroute-cache
no fair-queue
clockrate 64000
bridge-group 20
!
interface TokenRing0
no ip address
no ip route-cache
no ip mroute-cache
ring-speed 16
bridge-group 20
!
!
bridge 20 protocol ieee
bridge 20 bitswap-layer3-addresses
It was that last statement that I neglected to add when I first tried this.
The same result should be possible with SR/TLB, but I wasn't able to make it
work correctly. I'll have to play around and see what I can come up with.
The tricky portion of this is that on R2 and R3, ip routing is turned off.
I suppose I could still use RSRB on R2 and R3 since they're directly
connected. In fact, that's probably the way to go if the token ring segment
is using SRB.
Regards,
John
