In a Cisco, Huawei, or Juniper environment that is using LDP signaling to establish L2VPNs, MPLS Manager discovers the PE devices and the LDP speakers that are associated with the L2VPNs. It creates an LdpProtocolEndpoint instance for each discovered LDP speaker, and sets the IsTargetedPeer attribute of each instance to True, to indicates that each instance’s termination point is to a targeted peer.
LDP-signaled L2VPNs use LDP signaling to construct, advertise, maintain, and delete pseudowires.
The LdpProtocolEndpoint relationship Peer points from an LdpProtocolEndpoint to the LdpProtocolEndpoint at the other end of the LDP session. Because an LDP session is TCP-based, a peer LdpProtocolEndpoint can terminate on a PE device that is multiple Layer 3 hops away.
