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.
Perform the following configuration in MPLS view.
LDP Configuration The following sections describe the required LDP configuration tasks for MPLS
basic capability:
■ “Enabling LDP protocol”
■ “Enabling LDP on a VLAN interface”
The following sections describe the optional LDP configuration tasks for MPLS
basic capability:
■ “Configuring Remote-Peer for Extended Discovery Mode”
■ “Configuring session parameters”
Enabling LDP protocol To configure LDP, first enable LDP.
Perform the following configuration in the system view.
