Sets the interval between LDP Hello messages for LDP sessions for LDP interfaces. These messages maintain LDP sessions between the device and its LDP peers.
For an LDP interface configuration, the default value is the interval for the configured global LDP Hello messages.
MPLS interface LDP configuration mode
Use this command to set the interval for LDP Link Hello messages that are multicast to all routers on the subnet.
When you configure the LDP link interval for an interface, it overrides the global interval.
When a Hello Adjacency already exists, the adjacency remains up and any new configured interval takes effect upon the expiration of the current Hello Interval timer. Consequently, the next and subsequent Hello messages are sent at the new interval.
Use the no for this command to reset the default interval.
The following example sets the link Hello message interval for the interface to 30 seconds.
device# configure terminal device(config)# router mpls device(config-router-mpls)# mpls-interface ethernet 1/2 device(config-router-mpls-interface-1/2)# ldp-params device(config-router-mpls-interface-1/2-ldp-params)# hello-interval 30
