R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

463
NOTE:
• Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specif
y
an interval for the two levels respectively. On a P2P link, Level-1 and Level-2 packets are both sent in P2P
hello packets, and you need not specify an interval for two levels respectively.
• You can configure keywords level-1 and level-2 only on broadcast interfaces. Before doing that, you
need to enable IS-IS on the interface.
• As the shorter the interval is, the more system resources will be occupied, you should confi
g
ure a proper
interval as needed.
• If no level is specified, the hello interval applies to both Level-1 and Level-2.
• This command is not supported in loopback interface view.

Description
Use isis timer holding-multiplier to specify the IS-IS hello multiplier.
Use undo isis timer holding-multiplier to restore the default.
The default IS-IS hello multiplier is 3.
With the IS-IS hello multiplier configured, a router can uses hello packets to notify its neighbor router of
the adjacency hold time (hello multiplier times hello interval). If the neighbor router receives no hello
