Parameters
cipher: Sets a ciphertext authentication key.
plain: Sets a plaintext authentication key.

a plaintext string of 1 to 16 characters.
Usage guidelines
RSVP authentication ensures integrity of RSVP messages, preventing fake resource reservation requests
from occupying network resources.
RSVP uses MD5 to calculate a digest for the authentication key and the message body, adds the digest
to the message, and sends the message. When the peer receives the message, it performs the same
calculation and compares the calculated digest with the digest in the message. If the two digests are the
same, the message passes the RSVP authentication and is accepted. Otherwise, the peer device discards
the message.
RSVP authentication can be configured in the following views:
• RSVP view—Configuration in this view applies to all RSVP messages.
• RSVP neighbor view—Configuration in this view applies only to RSVP messages received from and
sent to the specified neighbor.
