Statement introduced in Junos OS Release 9.0 for EX Series switches.

Description
Enable authentication on an interface for hello packets. If you enable authentication on hello packets, you must specify a password by including the hello-authentication-key statement.
You can configure authentication for a given IS-IS level on an interface. On a point-to-point link, if you enable hello authentication for both IS-IS levels, the password configured for Level 1 is used for both levels.
 | Caution: If no authentication is configured for Level 1 on a point-to-point link with both levels enabled, the hello packets are sent without any password, regardless of the Level 2 authentication configurations. |
Default
By default, hello authentication is not configured on an interface. However, if IS-IS authentication is configured, the hello packets are authenticated using the IS-IS authentication type and password.
Options
md5—Specifies Message Digest 5 as the packet verification type.
simple—Specifies simple authentication as the packet verification type.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
