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

interface fastethernet4/0.2
ip address 4.4.4.1 255.255.255.0
encapsulation isl 12
The following is the configuration for the Catalyst 5000 switch with the Ethernet module in slot 2 and a
Token Ring switch module in slot 5. In this configuration, the Token Ring port is assigned with TrCRF
VLAN 100 and the Ethernet port is assigned with VLAN 12.
