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.
