Token ring vlan v.s. Subnet

Hi,

In a ethernet vlan, usually on vlan is mapped to one ip subnet. In token ring vlan enviroment, is there any mapping among TrBRF vlan, TrCRF vlan, and ip subnet?

Thanks for you help.

Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer.

Re: Token ring vlan v.s. Subnet

For token ring vlans a TrBRF vlan would be the parent of the child CRF's as a layer2 vlan. So for a IP subnet basically a 1 to 1 relation CAN exist for TrBRF's and there child CRF vlans.

So you can configure a subnet on a router with a BRF vlan and for all the child CRF vlans, they would be all part of the same subnet that the BRF lives in.
