Usage guidelines
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 met:
• 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.
