Configuring Routing Between VLANs

Configuration Examples for Configuring Routing Between VLANs

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 1 is assigned to the TrCRF VLAN 40:

#vtp

set vtp domain trisl

set vtp mode server

set vtp v2 enable

#drip

set set tokenring reduction enable

set tokenring distrib-crf disable

#vlans

set vlan 999 name trbrf type trbrf bridge 0xe stp ieee

set vlan 200 name trcrf200 type trcrf parent 999 ring 0x64 mode srt

set vlan 40 name trcrf40 type trcrf parent 999 ring 0x1 mode srt

#add token port to trcrf 40

set vlan 40 5/1

set trunk 1/2 on

VIP Distributed Switching over ISL Configuration: Example

Figure 90 shows a topology in which Catalyst VLAN switches are connected to routers forwarding

traffic from a number of ISL VLANs. With the VIP distributed ISL capability in the Cisco 7500 series

router, each VIP card can route ISL-encapsulated VLAN IP traffic. The inter-VLAN routing capacity is

increased linearly by the packet-forwarding capability of each VIP card.
