By default, the labels of all destination addresses are advertised to all LDP peers.

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.

Perform the following configuration in MPLS view.
