Ying: When using SRB you use multiring on the routers to generate a RIF as
you did.
The bridge checks the RIF and will discard the frame if the target ring is a
ring already
in the RIF. This is for loop prevention.
You do not need the source-bridge commands on the router TR interfaces if
you
are bridging thru the switch, as you noted.
HTH, Fred
