5. Configure CE 2:
# Configure an IP address for Ethernet1/1.

Verifying the configuration
# Execute the display l2protocol-tunnel command on PE 1 and PE 2 to display L2PT statistics.
Configuring L2PT and BPDU interoperation
Network requirements
As shown in Figure 37, a service provider network consists of an MPLS network and a metro Ethernet. CE
1 and CE 2 are edges devices on the geographically dispersed network of a user. The customer networks
reside in VLAN 2. CE 1 and CE 2 implement consistent MSTP calculation across the service provider
network.
• Create a Martini VC within the MPLS network so CE 1 and CE 2 can exchange Layer 2 packets
across the MPLS network.
• Configure L2PT on PE 1. Enable BPDU tunneling on PE 3, and replace the destination MAC address
of STP packets with multicast MAC address 0100-0CCD-CDD0 to avoid packet conflict.
• Configure Ethernet 1/2 on PE 3 as an access port, and assign the port to VLAN 2.
• Configure Ethernet 1/2.2 on PE 2 to terminate packets from VLAN 2.
• Configure Ethernet 1/1 on PE 3 as a trunk port, and permit all VLANs to pass through the port.
