Isis Timer Holding-Multiplier - HP 5920 Series Command Reference Manual

Parameters
seconds: Specifies the interval in seconds for sending hello packets, in the range of 3 to 255.
level-1: Specifies the interval for sending Level- 1 hello packets.
level-2: Specifies the interval for sending Level-2 hello packets.
Usage guidelines
If a neighbor does not receive any hello packets from the router within the advertised hold time, it
considers the router down and recalculates the routes. The hold time is the hello multiplier multiplied by
the hello interval.
Level- 1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify
an interval for each level. 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 each level.
You can configure keywords level-1 and level-2 only on broadcast interfaces. Before you do that, enable
IS-IS on the interface.
The shorter the interval, the more system resources will be occupied. Configure a proper interval as
needed.
If no level is specified, the hello interval applies to both Level- 1 and Level-2.
Examples
# Configure Level-2 hello packets to be sent every 20 seconds over VLAN-interface 10.
