Configuration Tasks for L2VPN
Example 20-12 shows how to configure VC 123 in Ethernet port mode:
Example 20-12 Ethernet over MPLS in Port Mode
pseudowire-class ethernet-port
encapsulation mpls
interface gigabitethernet1/0
xconnect 10.0.0.1 123 pw-class ethernet-port
Note Depending on the interface type, you can also use the interface fastethernet command.
Verifying Ethernet over MPLS in VLAN Mode and Port Mode
To determine if a VC is set up in VLAN mode or port mode, issue the show mpls l2transport vc
command.
Example 20-13 shows two VCs set up for Ethernet over MPLS:
• VC 2 is set up in Ethernet VLAN mode.
• VC 8 is set up in Ethernet port mode.
Example 20-13 show mpls l2transport vc Command Output
Router# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Gi4/0.1 Eth VLAN 2 11.1.1.1 2 UP
Gi8/0/1 Ethernet 11.1.1.1 8 UP
If you issue the show mpls l2transport vc detail command, the output is similar, as shown in
Example 20-14.
Example 20-14 show mpls l2transport vc detail Command Output
Router# show mpls l2transport vc detail
Local interface: Gi4/0.1 up, line protocol up, Eth VLAN 2 up
Destination address: 11.1.1.1, VC ID: 2, VC status: up
...
Local interface: Gi8/0/1 up, line protocol up, Ethernet up
Destination address: 11.1.1.1, VC ID: 8, VC status: up
