In an environment that is using LDP signaling to establish LSPs, the MPLS Topology Server discovers the PE and P devices and the LDP speakers that are associated with the LSPs. All links in the environment have interior gateway protocol adjacencies as well as LDP adjacencies. The complete MPLS forwarding path for an LDP LSP is determined by IP forwarding.
The MPLS Topology Server creates an LdpProtocolEndpoint instance for each discovered LDP speaker that is associated with an LDP LSP. It sets the instance’s IsTargetedPeer attribute to False, to indicates that this instance’s termination point is to a non-targeted peer.
Here are some relationships that are created for LdpProtocolEndpoint (non-targeted):
LdpProtocolEndpoint relationship HostedBy
Relates an LdpProtocolEndpoint to the PE or P device that hosts the LDP speaker that is represented by the LdpProtocolEndpoint.
LdpProtocolEndpoint relationship LayeredOver
Points from an LdpProtocolEndpoint to the interface and IP address, on the host PE or P device, that are associated with the LdpProtocolEndpoint.
LdpProtocolEndpoint relationship Peer
Points from an LdpProtocolEndpoint to the endpoint at the other end of the LdpAdjacency.
