LDP Configuration
517
By default, the labels of all destination addresses are advertised to all LDP peers.
Configuring Static LSP
You can manually set an LSR to be a node along an LSP, and place a limit on the
traffic over the LSP. Depending on the position in an MPLS domain, an LSR along
an LSP can be the ingress node, an intermediate node (also called transit node), or
the egress node. Note that an LSP operates normally only after all the LSRs along
the LSP have been properly configured.
