The LDP Layer 2 VPN implementation includes support for:
LDP signaling support for pseudowire ID (PWid) FEC for pseudowire (PW) establishment.
Use of LDP, RSVP-TE, or Static to establish transport LSPs.
Tunnel endpoints, identified via configured IP addresses.
Different VLAN IDs at each end of a PW, with the VLAN ID set by the egress switch to match that of the locally configured VLAN.
Operations as VPLS, H-VPLS, or VPWS node.
VLAN, VMAN, and port edge services (no port-qualified VLAN service).
Flooding of Layer 2 packets to multiple PWs when operating as a VPLS or H-VPLS node.
Note
The implementation does not include support for pseudowire participation in running the Spanning Tree Protocol.
