Task
Step 1 Modify an existing FDDI or FDDI NET-type

•
•
•
•
•
You must use VTP version 2 to configure and manage the Token Ring VLANs.

Understanding How Token Ring TrBRF VLANs Work

The Token Ring Bridge Relay Function (TrBRF) VLANs interconnect multiple the Token Ring
Concentrator Relay Function (TrCRF) VLANs in a switched Token Ring network (see
TrBRF can be extended across a network of switches that are interconnected through the trunk links. The
connection between the TrCRF and the TrBRF is referred to as a logical port.
