Configuring Ldp Sessions - Huawei Quidway S9300 series Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - MPLS
By default, the LSR ID of the LDP instance is the same as that set in
ID. You are recommended to use the default value.
Generally, LDP instances adopt default LSR IDs. In a certain networking solution where VPN
instances are adopted, such as BGP/MPLS VPN network, if the VPN address space and the
public network address space overlap, you need to configure LSR IDs for LDP instances to
ensure successful setup of TCP connections.

2.3.5 Configuring LDP Sessions

MPLS LDP sessions are classified into the locate LDP session and the remote LDP session.
Context
The MPLS LDP session is classified into the local LDP session and the remote LDP session.
You can choose one of the following configurations according to your demands:

Issue 04 (2011-12-26)
Configure local LDP session
Configure remote LDP session
The remote LDP session is set up between two indirectly connected LSRs. The remote LDP
session is applied in the following situations:
– Configuring a VLL or VPLS in Martini mode
Configuring a local LDP session
Do as follows on two directly connected LSRs. If an LDP session is set up between two
directly-connected LSRs, an LDP LSP is set up between these two LSRs. For details of
LDP LSPs, see Configuring LDP
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The view of the interface on which LDP session is to be set up is displayed.
NOTE
Before enabling the LDP function, you must enable the MPLS function on the interface.
3. Run:
mpls ldp
MPLS LDP is enabled on the interface.
By default, MPLS LDP is disabled.
NOTE
Disabling LDP on the interface may interrupt all LDP sessions on the interface. In addition, all
the LSPs based on these sessions are deleted accordingly.
