Configuring Routing Between VLANs
Configuration Examples for Configuring Routing Between VLANs
54
As shown in Figure 84, AppleTalk traffic is routed to and from switched VLAN domains 3, 4, 100, and
200 to any other AppleTalk routing interface. This example shows a sample configuration file for the
Cisco 7500 series router with the commands entered to configure the network shown in Figure 84.

Banyan VINES Routing over ISL Configuration: Example
To configure routing of the Banyan VINES protocol over ISL trunks, you need to define ISL as the
encapsulation type. This example shows Banyan VINES configured to be routed over an ISL trunk:
vines routing
interface fastethernet 0.1
encapsulation isl 100
vines metric 2
DECnet Routing over ISL Configuration: Example
To configure routing the DECnet protocol over ISL trunks, you need to define ISL as the encapsulation
type. This example shows DECnet configured to be routed over an ISL trunk:
decnet routing 2.1
interface fastethernet 1/0.1
encapsulation isl 200
decnet cost 4
HSRP over ISL Configuration: Example
The configuration example shown in Figure 85 shows HSRP being used on two VLAN routers sending
traffic to and from ISL VLANs through a Catalyst 5000 switch. Each router forwards its own traffic and
acts as a standby for the other.
