Hi Kyle,
I also tried that same config that you have below. Still didnt work.
I would greatly appreciate it if you could give some feedback when you tested t
he same setup as mine in your lab. I only rented an online rack to play around
with 3920.
Thanks very much.
Neil

did you try assigning a ring number to the 3900 instead of using auto
mode? Do the router show a ring number? I know I've seen mismatches
when the ring numbers where different., But that was when I had srb also
configed on the router interface like this
source-bridge ring-group 100
Inter to0
source-route 5 1 100
If the 3900 is attached to to0 it should see ring 5 I believe. I'll try it
in the lab later today.
