Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
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 PWs, see the “Transportation of Service Using Ethernet over
MPLS” section on page 1-4.
Configuring VLAN Mode
An Ethernet over MPLS PW in VLAN mode creates a connection based on an existing VLAN ID on the
Cisco MWR 2941.
Step 1 Create the VLAN interface that you want to bind to a pseudowire.
Router(config)# interface vlan 100
Router(config-if)#
Step 2 Use the xconnect command to 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.
Router(config-if)# xconnect 1.1.1.2 101 encapsulation mpls
Step 3 Add the GigabitEthernet interface to the VLAN.
Router(config-if)# interface GigabitEthernet 0/1
Router(config-if)# switchport trunk allowed vlan 100
Router(config-if)# switchport mode trunk
Step 4 Create a corresponding configuration on the remote router with the same VCID value. This
configuration uses VCID 101.
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.
Note When creating IP routes with 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
1.1.1.2 255.255.255.255 1.2.3.4.
Note For more information about configuring VLANs on the Cisco MWR 2941, see Configuring Gigabit
Ethernet Interfaces, page 4-4.
