User & Password

When a server’s authorization parameter is enabled, other servers that actively connect to it must authenticate themselves by name and password, or by X.509 certificate.

In the above image, servers A and B both configure active routes to one another.

  • Because A enables authorization, A must configure a user named B.
  • However, because B disables authorization, A need not identify itself to B, and B need not configure a user named A.
