NOTE
PWE3 does not support point-to-multipoint (P2MP). When you create an MPLS L2VC on an ATM sub-
interface, the ATM sub-interface must be in the point-to-point (P2P) type. When you configure the
transparent transmission of ATM cells, the type of the ATM sub-interface is not restricted.
# Configure U-PE1.
[U-PE1] mpls l2vpn
[U-PE1-l2vpn] quit
[U-PE1] interface vlanif 10
[U-PE1-Vlanif10] mpls l2vc pw-template pwt 100
[U-PE1-Vlanif10] quit
# Configure S-PE.
[S-PE] mpls l2vpn
[S-PE-l2vpn] quit
[S-PE] mpls switch-l2vc 1.1.1.9 100 between 5.5.5.9 200 encapsulation vlan
# Configure U-PE2.
[U-PE2] mpls l2vpn
[U-PE2-l2vpn] quit
[U-PE2] interface vlanif 60
[U-PE2-Vlanif60] mpls l2vc pw-template pwt 200
[U-PE2-Vlanif60] quit
After the preceding configuration, run the display mpls l2vc interface command on U-PEs to
check L2VPN connections. You can see that PWs are set up and in Active state. In addition, you
can find that the BFD for PW function is disabled on the PWs.
Take the display on U-PE1 for example.
