Release Information

Command introduced before JunosE Release 7.1.0.

Description

Specifies an HMAC MD5 key that the router uses to create a secure, encrypted message digest of IS-IS level 1 or level 2 hello packets on the interface. Level 1 packets are the default. The digest is inserted into the packet from which it is created. Using this algorithm protects against intrusion by preventing unauthorized routers from forming adjacencies with your router.

You can specify when the router will start (default is the current time) and stop (default is never) accepting packets that include a digest made with this key. You can specify when the router will start (default is the current time plus 2 minutes) and stop (default is never) generating packets that include a digest made with this key. The no version deletes the key specified by the keyId.
