Static PW configuration example
Network requirements
CEs are connected to the PEs through Layer 3 Ethernet interfaces (GigabitEthernet 2/1/1).
Configure a VSI 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.

# Enable global LDP.
