Configuring Routing Between VLANs
Configuration Examples for Configuring Routing Between VLANs
62
CLNS Routing over ISL Configuration: Example
To configure routing of the CLNS protocol over ISL trunks, you need to define ISL as the encapsulation
type. This example shows CLNS configured to be routed over an ISL trunk:
clns routing
interface fastethernet 1/0.1
encapsulation isl 100
clns enable
IS-IS Routing over ISL Configuration: Example
To configure IS-IS routing over ISL trunks, you need to define ISL as the encapsulation type. This
example shows IS-IS configured over an ISL trunk:
isis routing test-proc2
net 49.0001.0002.aaaa.aaaa.aaaa.00
interface fastethernet 2.0
encapsulation isl 101
clns router is-is test-proc2
Routing IEEE 802.10 Configuration: Example
The configuration example shown in Figure 91 shows AppleTalk being routed between different ISL and
IEEE 802.10 VLAN encapsulating subinterfaces.
Figure 91 Routing AppleTalk over VLAN encapsulations
As shown in Figure 91, 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 91.
