authentication algorithm

This command defines authentication algorithm.

The use of a negative form (no) of the command disables the authentication.

Syntax
authentication algorithm <ALGORITHM>
no authentication algorithm
Parameters

<ALGORITHM> – authentication algorithm:

  • cleartext – password, transmitted in unencrypted form (available only for CONFIG-RIP and CONFIG_OSPF-VLINK modes);
  • md5 – password is hashed by md5 algorithm.

authentication key

This command sets a password for authentication with a neighbor.

The use of a negative form (no) of the command removes the password.

Syntax
authentication key ascii-text { <CLEAR-TEXT> | encrypted <ENCRYPTED-TEXT> }
no authentication key
Parameters

<CLEAR-TEXT> – password, set by the string of 8 to 16 characters.

<ENCRYPTED-TEXT> – encrypted password of [8..16] bytes ([16..32] characters) in hexadecimal format (0xYYYY...) or (YYYY...).
