IP Routing Source-Routed Frames Between TRISL VLANs Example
Figure 58 illustrates IP routing source-routed frames between two TrBRF VLANs.

The following is the configuration for the router:
interface fastethernet4/0.1
ip address 5.5.5.1 255.255.255.0
encapsulation tr-isl trbrf-vlan 999 bridge-num 14
multiring trcrf-vlan 200 ring 100
multiring all
!
interface fastethernet4/0.2
ip address 4.4.4.1 255.255.255.0
encapsulation tr-isl trbrf-vlan 998 bridge-num 13
multiring trcrf-vlan 300 ring 101
multiring all
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 attached to ring 102 is assigned with TrCRF VLAN 40
and the Token Ring port attached to ring 103 is assigned with TrCRF VLAN 50.
