IP Routing Non-Source-Routed Frames Between a TRISL VLAN and a Token
Ring Interface Example
Figure 55 illustrates IP routing between a TRISL VLAN and a Token Ring interface.
Figure 55 IP Routing Between a TRISL VLAN and a Token Ring Interface
The following is the configuration for the router:
ip routing

The following is the configuration for the Catalyst 5000 switch with the Token Ring switch module in
slot 5. In this configuration, the Token Ring port 1 is assigned to the TrCRF VLAN 40.
