Hi Christopher,
From an IP point of view, a TrBRF forms a vlan. Therefore, different
subnets=different TrBRF's. For routers on the same VLAN, use ports in the
same TrCRF. For routers in different VLANS, I believe that you need to
a) Do routing on a stick using a TrISL connection but I don't think 3920's
support it.
b) Use an RSM in a 5x00 and create two TrBRF interfaces.
c) Use two 3920's with a router with two TR interfaces. The TrBRF's would
reside on each 3920 and the router would route between them.
Regards,
Lachlan

I am trying to create a simple vlan between 2 routers (R1 and R2) that have
a TR interface connected to a single 3920. I would like each router to be
on the same vlan. I would like the other routers connected to the same 3920
to be on another vlan.
My understanding is you can have multiple TrCRF's interconnected by using 1
TrBRF. So my thinking is that I need to create at least 2 seperate TrCRF's
and assign R1 and R2 to one of the TrCRF's and the rest of the routers to
the other TrCRF. Am I on the right track? Because my set up is not working
properly....
Thanks in advance.
