The following is a sample from CISCO Document CD about Token ISL, i have one
question about it that can the VLAN 40 and 50 communication each other? The
answer i think is Yes, because they are source route bridge by the ring 101
in router. Am i right? Thanks.
This is the configuration about the router and CAT5000.
The following is the configuration for the router:
source-bridge ring-group 101
!
interface FastEthernet4/0.1
encapsulation tr-isl trbrf 999 bridge-num 14
source-bridge trcrf-vlan 100 ring-group 101
source-bridge spanning
!
interface FastEthernet4/0.2
encapsulation tr-isl trbrf 998 bridge-num 13
source-bridge trcrf-vlan 102 ring-group 101
source-bridge spanning
The following is the configuration for the Catalyst 5000 switch with the
Token Ring switch module in slot 5. The Token Ring port on 5/1 is assigned
to TrCRF VLAN 40 and the Token Ring port on 5/2 is assigned to TrCRF VLAN
50.
In this configuration, the keyword name is optional and srb is the default
mode.
