Hello
first you have to configure two VLAN's with two BRF's next you configure the
TrCRF's for every BRF. Then you put the ports to one of the TrCRF.
or look at

Betreff: RE: TokenRing Switching Configs.
Hi,
It is still not clear to me about what makes a
LIS (Logical IP Subnet):-(
Let's consider 10 ports on 3900. I want to have 5
ports (1-5) on one VLAN (172.16.1.0/24) and the other
5 ports (6-10) on another VLAN (172.16.2.0/24). I will
route between these two VLAN using an external router.
How to acheive this?
Mohan.
