Specifies the number of Intermediate System-to-Intermediate System (IS-IS) hello packets a neighbor must miss before the device declares adjacency as down.
The default is 3.
Interface subtype configuration mode
IS-IS is supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".
The hello multiplier is the number by which an IS-IS interface multiplies the hello interval to obtain the hold time for Level-1 and Level-2 IS-IS hello PDUs.
The no form of the command restores the default of 10 seconds.
The following example changes the hello multiplier for Level 1 packets for an Ethernet interface.
device# configure terminal device(config)# interface ethernet 1/1 device(conf-if-eth-1/1)# isis hello-multiplier level-1 10
The following example changes the hello multiplier for Level 2 packets for a loopback interface.
device# configure terminal device(config)# interface loopback 1 device(config-Loopback-1)# isis hello-mulitplier level-2 20
