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 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.
Options
■
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—S tring 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 ].
