To configure ES-IS on an interface, include the following statements in the configuration:
- esis {
- interface (interface-name | all);
- disable;
- hello-interval seconds;
- esct seconds;
- }
For a list of hierarchy levels at which you can configure these statements, see the statement summary section for the esis statement.
ES-IS protocol is enabled automatically if the IS-IS protocol is configured and enabled. ES-IS does not need to be explicitly configured if IS-IS is enabled. If an interface is not configured as an ISO family interface, ES-IS will not run on it.
Specify the interface statement to configure an interface to send and receive hello messages. Specify the disable statement to stop sending or receiving ES-IS packets on the interface.
