Prefix-Label Advertise; Remote - HP 5800 series Command Reference Manual

prefix-label advertise

Description
Use the prefix-label advertise command to configure LDP to advertise prefix-based labels through remote
sessions.
Use the undo prefix-label advertise command to restore the default.
By default, LDP does not advertise prefix-based label through a remote session.
A device can advertise prefix-based labels to its remote peers through remote sessions only after you have
configured the prefix-label advertise command. However, a device can receive labels advertised by its
remote peers no matter whether you have configured this command or not.
After the device receives labels advertised by the peer, the corresponding LDP LSP can be established if
the following conditions are satisfied:
• The FEC's outgoing interface is the MPLS TE tunnel interface.
• The destination address of the MPLS TE tunnel, the remote peer address specified through the
remote-ip command, and the LSR ID of the remote peer are the same.
The MPLS TE tunnel interface is enabled with the MPLS capability.

Description
Use the remote-ip command to configure the remote peer IP address.
Use the undo remote-ip command to remove the configuration.
The remote peer IP address must be the MPLS LSR ID of the remote peer. Two peers use their MPLS LSR
IDs as the transport addresses to establish the TCP connection.
