Configuring MPLS over VLAN

To configure MPLS over VLAN over an Ethernet interface:

1. Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet port.

   host1(config)#interface fastEthernet 4/0

2. Specify VLAN as the encapsulation method.

   host1(config-if)#encapsulation vlan

   The VLAN major interface is added.

3. Create a VLAN subinterface by adding a subinterface number to the interface identification command.

   host1(config-if)#interface fastEthernet 4/1.1

4. Do one of the following:
   • Assign a VLAN ID for the subinterface.

     host1(config-if)#vlan id 400

   • Assign a VLAN ID and the optional unique MAC address for the subinterface.

     host1(config-if)#vlan id 400 mac-address 0090.1a01.1234

5. Enable MPLS on the interface.

   host1(config-if)#mpls
