Parameters

value: Specifies the number of hello intervals, in the range of 3 to 1000.

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 the level-1 and level-2 keywords only on broadcast interfaces. Before you configure the level-1 or level-2 keyword, enable IS-IS on the interface.

If no level is specified, the hello multiplier applies to both Level-1 and Level-2.

The value of hello multiplier multiplied by hello interval cannot be more than 65535.

Examples

# Set the hello multiplier to 6 for VLAN-interface 10.

<Sysname> system-view
[Sysname] interface vlan-interface 10
