peer-lsr-id: MPLS LSR ID of the peer. An LSR and its peer must use the same password.
password: Password string, case sensitive. If you specify the plain keyword, it must be a string of 1 to
16 characters in plain text. If you specify the cipher keyword, it can be either a string of 1 to 16
characters in plain text or a string of 24 characters in cipher text.
Description
Use the md5-password command to enable LDP MD5 authentication and set the password, which
must be the same as that configured on the peer.
Use the undo md5-password command to disable LDP MD5 authentication.
By default, LDP MD5 authentication is disabled.
Changing the password will cause the sessions and all LSPs based on the sessions to be removed.
This command takes effect only after MPLS LDP is enabled in the corresponding view.
