Configuring Local Cross-Connects Between Ethernet/VLAN Interfaces

Figure 119: Local Cross-Connect Between Ethernet/VLAN Interfaces

Copyright © 2010, Juniper Networks, Inc.
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 533 shows the interface stack that the router builds for this configuration.
To configure the application shown in Figure 119 on page 533:
Configure a local IP address.
1.
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.
2.
host1(config)#interface fastEthernet 9/1
host1(config-if)#encapsulation vlan
host1(config-if)#exit
host1(config)#interface fastEthernet 9/1.1
host1(config-if)#vlan id 10
(Optional) If you are configuring a multiservice local cross-connect, assign an IP
3.
address and mask to the Ethernet/VLAN interface.
host1(config-if)#ip address 10.1.2.3 255.255.255.0
Configure MPLS tunneling on this side of the connection by issuing the mpls-relay
4.
command.
