Note Normally, active transmission of targeted hello messages on a router is triggered by some
configuration action, such as an mpls ip command on a traffic engineering tunnel interface.
Examples The following example shows how to set the period of time to 30 seconds for which a neighbor
discovered on an interface is remembered, if no hello messages are received:
Router# configure terminal
Router(config)# mpls ldp discovery hello holdtime 30
The following example shows how to configure the router to respond to requests for targeted hello
messages from neighbors 209.165.200.225 and 209.165.200.234:
Router(config)# ip access standard TRGT-ACCEPT
Router(config-nacl)# permit 209.165.200.225
Router(config-nacl)# permit 209.165.200.234
Router(config-nacl)# exit
