Sets the interval between LDP link Hello messages globally which applies to all LDP interfaces. These messages are used to maintain LDP sessions between the device and its LDP peers.
The default is 5 seconds.
MPLS LDP configuration mode
Use this command to globally set the interval for LDP Link Hello messages that multicast to all routers on the subnet.
When you configure the LDP link interval for an interface, it overrides the global interval for the interface.
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.
MPLS is supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".
The following example sets the global interval to 10 seconds.
device# configure terminal device(config)# router mpls device(config-router-mpls)# ldp device(config-router-mpls-ldp)# hello-interval-link 10
