Configuring Pseudowire
Configuring Transportation of Service Using Ethernet over MPLS
Ethernet over MPLS PWs allow you to transport Ethernet traffic over an existing MPLS network. For an
overview of Ethernet over MPLS pseudowires, see Transportation of Service Using Ethernet over MPLS,
page 23-3.
Configuring VLAN Mode
An Ethernet over MPLS pseudowire in VLAN mode creates a connection based on an existing VLAN
ID on the Cisco MWR 2941. Follow these steps to configure an Ethernet over MPLS pseudowire in
VLAN mode.
Note The Cisco MWR 2941 supports VLAN rewriting on EoMPLS PWs. If the two networks use different
VLAN IDs, the router rewrites PW packets using the appropriate VLAN number for the local network.
Command Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
Router(config)# interface vlan 100
Creates the VLAN interface to bind to a pseudowire.
Step 4
Router(config-if)# xconnect 1.1.1.2
101 encapsulation mpls
Binds the Ethernet port interface to an attachment circuit to create a
pseudowire. This example uses virtual circuit (VC) 101 to uniquely
identify the PW. Ensure that the remote VLAN is configured with the
same VC.
Note When creating IP routes for a pseudowire configuration, we
recommend that you build a route from the xconnect address
(LDP router-id or loopback address) to the next hop IP address,
such as ip route 30.30.30.2 255.255.255.255 1.2.3.4.
Step 5
Router(config-if)# interface
GigabitEthernet 0/1
Router(config-if)# switchport trunk
allowed vlan 100
Router(config-if)# switchport mode
trunk
Adds the GigabitEthernet interface to the VLAN.
Step 6
Creates a corresponding configuration on the remote router with the same
VCID value. This configuration uses VCID 101.
Step 7
exit
Example:
Router(config)# exit
Router#
Exits configuration mode.
