2.2 The Basic Message Interaction Flow of
For example, use to implement AAA on a telnet user, and the basic
message interaction flow described below is used:
1) A user requests access to the router. The router( client) sends the
authentication start packet to the server upon receipt of the request.
2) The server sends an authentication response packet requesting the
user name. The router ( client) asks the user for the user name upon
receipt of the response packet.
3) After receiving the user name from the user, the router ( client) sends
the authentication packet to the carrying the user name.
4)
The server sends back an authentication response packet, requesting
the login password. Upon receipt of the response packet, the router (
client) requests the user for the login password.
5) The router ( client) sends an authentication packet carrying the login
password to the server.
6) The server sends back the authentication response packet indicating
that the user has passed the authentication.
7) The router ( client) sends the user authorization packet to the
server.
8) The server sends back the authorization response packet, indicating
that the user has passed the authorization.
9) Upon receipt of the response packet indicating an authorization success, the
router ( client) pushes the configuration interface of the router to the
user.
10) The router ( client) sends the accounting start request packet to the
server
11) The server sends back an accounting response packet, indicating that
it has received the accounting start request packet.
12) The user quits, and the router ( client) sends the accounting stop
packet to the server.
13) The server sends back the accounting stop packet, indicating that the
accounting stop request packet has been received.
The following figure illustrates the basic message interaction flow:
