level-1: Applies the number to the Level-1 IS-IS neighbor.
level-2: Applies the number to the Level-2 IS-IS neighbor.
Usage guidelines
The hello multiplier is the number of hello packets a neighbor must miss before declaring the router is
down.
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
a hello multiplier 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 Level-1 or Level-2.
You can configure keywords level-1 and level-2 only on broadcast interfaces. Before doing that, enable
IS-IS on the interface.
If no level is specified, the hello multiplier applies to the current level.
The value of hello multiplier multiplied by hello interval cannot be more than 65535.
Examples
# Configure the hello multiplier as 6 for Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] isis timer holding-multiplier 6 level-2
