Command introduced before JunosE Release 7.1.0.
Specifies an HMAC MD5 key that the router uses to create a secure, encrypted message
digest of each IS-IS level 1 packet (LSPs, CSNPs, and PSNPs). The digest is inserted into
the packet from which it is created. Using this algorithm for area routers protects against
unauthorized routers injecting false routing information into your network.
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.
NOTE: Issuing this command enables MD5 authentication of level 1 LSPs
only. To enable authentication of level 1 CSNPs or PSNPs, use the
area-authentication command.
keyId—Integer from 1 to 255 that is a unique identifier for the secret key, sent with the
message digest in the packet.
0—Indicates the key is entered in unencrypted form (plaintext); default option
8—Indicates the key is entered in encrypted form (ciphertext)
key—String of up to 20 alphanumeric characters; secret key used by the HMAC MD5
algorithm to generate the message digest
startAcceptTime, startAcceptMonth, startAcceptDay, startAcceptYear—Time, month,
day, year that the router will start accepting packets created with this password. Use
military time format HH : MM[: SS ].
startGenTime, startGenMonth, startGenDay, startGenYear—Time, month, day, year that
the router will start inserting this password into packets. Use military time format HH
: MM[: SS ].
