Configuring Integrated IS-IS

IS-IS Interface Parameters Configuration Task List

Setting the Hello Multiplier

To specify the number of IS-IS hello packets a neighbor must miss before the router should declare the adjacency as down, use the following command in interface configuration command. The default value is 3.

Command	Purpose
Router(config-if)#isis hello-multiplier multiplier	Sets the hello multiplier.
[level-1 level-2]

Specifying Designated Router Election

You can configure the priority to use for designated router election. Priorities can be configured for Level 1 and Level 2 individually.

To specify the designated router election, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)#isis priority number-value[level-1	Configures the priority to use for designated router
level-2]	election.

Specifying the Interface Circuit Type

You can specify adjacency levels on a specified interface. This parameter is also referred to as the interface circuit type.

To specify the interface circuit type, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)#isis circuit-type [level-1	Configures the type of adjacency desired for neighbors on
level-1-2 level-2-only]	the specified interface (the interface circuit type).

Assigning a Password for an Interface

You can assign different passwords for different routing levels. Specifying Level 1 or Level 2 configures the password for only Level 1 or Level 2 routing, respectively. If you do not specify a level, the default is Level 1. By default, authentication is disabled.

To configure a password for the specified level, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)#isis password password [level-1	Configures the authentication password for a specified
level-2]	interface.
