isis hello-multiplier

---

Configures the hello multiplier to use on this interface.

Syntax: [no] isis hello-multiplier number

number

The multiplier used to determine how long to hold an IS-IS hello packet before declaring an adjacency down. Valid values are 3 - 1000.

Description: Each hello packet sent from an intermediate system contains a hold timer field. This field tells the receiving intermediate system how long to wait for another hello packet before declaring the adjacency down.

If the hello interval is 10 seconds and the hello multiplier is 5, the adjacent intermediate system will wait 50 seconds for a hello packet from this adjacent intermediate system before declaring the adjacency down.

Use the isis hello-multiplier number command to configure the multiplier for this interface.

Use the no isis hello-multiplier to configure the multiplier as the default value of 10.

Factory Default: 10 times hello interval.

Command Mode: Interface configuration.

Example: In the following example:

• The router isis command enables IS-IS on the router, specifies an IS-IS instance, and changes the command mode to Router configuration.
  
  
• The net command configures a NET for the routing process.
  
  
• The interface pos n/n/n identifies a specific POS interface and changes the command mode to Interface configuration.
  
  
• The ip router isis command enables the IS-IS process specified by the global router isis command on the interface.
  
  
• The isis hello-interval command configures the hello timer for the interface at 15.
  
  
• The isis hello-multiplier command configures the hello multiplier to 5 times the hello interval.
  
  
• The show running-config interface command displays the setting:
