Optional) Configuring Ldp Timers - Huawei Quidway S9300 series Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - MPLS
An LDP transport address is specified as the IP address of a specified interface.
By default, the LDP transport address in the public network is the LSR ID set in
an LSR
If multiple links exist between two LSRs and you intend to establish an LDP session on these
links, the interfaces on the same side of the session must adopt the default transport address or
be configured with the same transport address; otherwise, the LDP session is established only
on one link.
There are two methods of configuring LDP sessions on multiple links:
l Use LSR IDs to set up LDP sessions for each link.
l Each link adopts the LDP transport address specified through the mpls ldp transport-

2.3.7 (Optional) Configuring LDP Timers

LDP timers are classified into Hello hold timer, Hello send timer, Keepalive hold timer,
Keepalive send timer, and the Exponential backoff timer, which can be configured as required.
Context
You are recommended to set the value of a timer equal to or greater than the default value. When
many LDP sessions are set up between LSRs or the CPU usage is high, the status of LDP sessions
may frequently switch between Up and Down if the value of the timer is smaller than the default
value. Increasing the values of timers can improve the stability of LDP sessions.
LDP timers are classified into Hello hold timer, Hello send timer, Keepalive hold timer,
Keepalive send timer, and the Exponential backoff timer.

address command for the same interface.
NOTE
In the case of LDP multi-instance, each instance can have a specific TCP connection.
CAUTION
Hello hold timers are classified into the following timers:
– Link-Hello hold timer
– Targeted-Hello hold timer
Hello send timers are classified into the following timers:
– Link-Hello send timer
– Targeted-Hello send timer
Keepalive hold timers are classified into the following timers:
– Keepalive hold timers of local LDP session
– Keepalive hold timers of remote LDP session
Keepalive send timers are classified into the following timers:
– Keepalive send timer of local LDP session
