Transparent Bridging Between Token Ring and TRISL VLAN Example
Figure 65 illustrates transparent bridging between a router’s Token Ring interface and a TRISL VLAN.
Figure 65 Transparent Bridging Between Token Ring and TRISL VLAN
The following is the configuration for the router:
bridge 1 protocol ieee
!
interface Tokenring0
bridge-group 1
!
interface fastethernet0/0.1
encapsulation tr-isl trbrf-vlan 50 bridge-num 11
bridge-group 1
The following is the configuration for the Catalyst 5000 switch with a Token Ring switch module in
slot 5:
#vtp
set vtp domain trisl
set vtp mode server
set vtp v2 enable
#drip
set tokenring reduction enable
set tokenring distrib-crf disable
#vlans
set vlan 50 name trbrf50 type trbrf bridge 0xb stp ieee
set vlan 100 name trcrf100 type trcrf ring 0x14 parent 50 mode srt
#enable trunk
set trunk 1/2 on
#add token port to trcrf 100
set vlan 100 5/1
