information sent from unreliable routers. If available with the route authentication
function, a router will be able to authenticate the switching route update packets
received from the neighboring routers and hence make sure to receive only the reliable
route information.
II. Authentication Implementation
The routers exchanging route information share the same password key that is sent
along with the route information packets. The routers receiving the route information
will authenticate the packets, and verify the password key carried by the packets. If the
key carried by the packets is the same as the shared password key, the packets will be
accepted. If not, they will be discarded.
Authentication implementations fall into simple text authentication and MD5
authentication. The former sends password keys in plain text providing lower security,
whereas the latter sends encrypted password keys providing higher security.
