Enabling Ldp Protocol; Enabling Ldp On Vlan Interface; Configuring Remote-Peer For Extended Discovery Mode - H3C S9500 Series Operation Manual

Operation Manual – MPLS
H3C S9500 Series Routing Switches

2.3.1 Enabling LDP protocol

To configure LDP, first enable LDP.
Perform the following configuration in the system view.
Table 2-5 Enable/disable LDP view
Enable LDP protocol
Disable LDP
By default, LDP is disabled.

2.3.2 Enabling LDP on VLAN interface

To make the VLAN interface support LDP, you must enable LDP function on the
interface in VLAN interface mode. After enabling the LDP function, the interface then
sets up session. It begins to set up LSP if in topology-driven mode,.
Disabling LDP function on interface causes the break of all LDP session in VLAN
interface, and all the LSP based on those sessions are deleted. So you must use this
command with cautiously.
Perform the following configuration in the interface view.
Table 2-6 Enable/disable LDP on interface
Enable LDP function on interface
Disable LDP function on interface
By default, the interface LDP function is disabled.

2.3.3 Configuring Remote-Peer for Extended Discovery Mode

The Remote-peer configuration is mainly used for extended discovery mode so that
this LSR can establish sessions with LSRs that are not directly connected with it at the
link layer.
