set protocols mpls ldp discovery targeted-hello-interval

The set protocols mpls ldp discovery targeted-hello-interval command configures the time interval for sending Targeted hello messages.

The delete protocols mpls ldp discovery targeted-hello-interval command deletes the configuration.

Command Syntax

set protocols mpls ldp [ipv4-family|ipv6-family] discovery targeted-hello-interval <hello-interval>

delete protocols mpls ldp [ipv4-family|ipv6-family] discovery targeted-hello-interval

Parameter

Parameter	Description
ipv4-family\|ipv6-family	Optional. Specifies the IP address family type.
targeted-hello-interval <hello-interval>	Specifies the time interval for sending Targeted hello messages. The value is an integer which can be configured between 1 and 65535 seconds. The default value is 15 seconds.

Usage Guidelines

This command plays a crucial role in the LDP discovery process, which is essential for the establishment and maintenance of LDP sessions between routers.

A shorter Hello interval results in more frequent Hello messages. This can help in quicker detection of peers going down, which might be critical in high-availability environments. However, it increases the processing load on the router and the amount of control traffic.

NOTEs：

Before configuring the discovery targeted-hello-interval and discovery targeted-hello-holdtime, the targeted-hello-accept under the IP family must be enabled first.
The configuration of discovery targeted-hello-interval and discovery targeted-hello-holdtime based on the IP family takes precedence over the global configuration.
For the discovery targeted-hello-interval configuration, the actual effective timer value equals the smaller of the timers configured on both ends of the LDP peers.

Example

Configure the interval for sending Targeted hello messages.
