Devender: Scenario 1 - correct, use 2 TrBRF's each with a single
TrCRF. Specify the ring numbers for the TrCRF's.
Scenario 2 - correct if you are configuring the three rings on r1 as
separate
networks (i.e., not in the same broadcast domain). The three token
rings could be bridged on the router with the same virtual ring
specified.
You could use a single TrBRF on r1 if you wanted to configure the three
token rings in a single broadcast domain (i.e. same IP network). Not
sure how this would be applied to DLSW.
Also not sure on the auto parameter. I always specify it. The 3900
switch ring number is specified in hex. The router ring number is
specified in decimal but I recommend you specify it as 0x(switch ring
number) to avoid conversion errors.
HTH, Fred
