Static PW configuration example
Network requirements
Configure VPLS on each PE, and establish static PWs between the PEs to interconnect the CEs.

Configuration procedure
This task includes the following configurations:
Configure basic MPLS on each PE: configure LSR ID, enable LDP, run IGP (OSPF in this example) to establish LSPs.
Establish static PWs: enable L2VPN, create static PWs, and specify labels.
Configure PE 1:
# Configure an LSR ID.
