Configuring Local Cross-Connects Between Ethernet/VLAN Interfaces
This section provides an example for configuring a local cross-connect that uses
MPLS between two Ethernet/VLAN interfaces.
NOTE: You must use the mpls-relay command instead of the route interface
command to configure a local cross-connect, regardless of the MPLS tunneling method
used in the core network.
Figure 119 on page 527 shows the interface stack that the router builds for this
configuration.

To configure the application shown in Figure 119 on page 527:
1.
2.
svlan ethertype
svlan id
Configure a local IP address.
You can use any reachable local IP address. This example uses a loopback
interface to provide the local IP address.
host1(config)#interface loopback 0
host1(config-if)#ip address 10.1.1.1 255.255.255.255
host1(config-if)#exit
Configure the Ethernet/VLAN interface on one side of the local cross-connect.
host1(config)#interface fastEthernet 9/1
host1(config-if)#encapsulation vlan
host1(config-if)#exit
host1(config)#interface fastEthernet 9/1.1
