Configuring Customer-Facing Interfaces in the L2VPN Instance

You must configure one of the following types of interfaces as a member of the L2VPN to transmit packets between the PE router and each CE device to which the PE router is connected:

• ATM (AAL5 VCC transport or ATM VCC cell transport)
• Cisco HDLC
• Ethernet (Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet)
• Frame Relay
• PPP
• VLAN and S-VLAN subinterfaces over Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interfaces

To configure a customer-facing interface for an L2VPN instance:

1. Access Interface Configuration mode for a layer 2 interface for the L2VPN on the PE router.

host1(config)#interface fastEthernet 4/0

2. Configure the local and remote site IDs on the interface to specify the interface as a member of the L2VPN.

host1(config-if)#l2vpn exampleco local-site-id 1 remote-site-id 2

host1(config-if)#exit

3. Repeat for all customer-facing interfaces in the L2VPN.

host1(config)#interface fastEthernet 4/1

host1(config-if)#l2vpn exampleco local-site-id 1 remote-site-id 3

host1(config-if)#exit
