PPP验证（The PPP authentication） The PPP authentication Verify the validation To verify the One by one A: : : : configuration steps Configure the step configuration steps Configuration steps: : : : 1: Verify that each router has assigned the host name. To assign a host name, enter it in global configuration mode The hostname name This name must match the user name expected by the authentication router at the other end of the link 2: Use the username name password password global configuration command on each router to define expectations from remote routing The user name and password obtained by the device. For example: username R3 password cisco Note: R3 is the right end The end-to-end For the host name of the router, cisco is the password, and the passwords on both ends must be the same. 3: use PPP authentication {chap | chap | pap chap | pap chap | pap} interface configuration command to configure PPP authentication. The second . 2: : : : PPP method Certificate form The way: : : : PAP and And and And the CHAP PAP is a two-way handshake, which provides a simple way for remote nodes to establish their identity. PAP is only in the initial link Execution during setup. The CHAP with three handshakes was set up on the link and then regularly used three handshakes to test the distance The identity of the path node. If the PPP authentication chap pap router is configured, try using the chap to validate all incoming The PPP session. If the remote device does not support chap, the router will try to validate PPP sessions using the pap. If the device doesnt Support for chap also does not support pap, authentication will fail. And the PPP session will be closed. If the PPP authentication pap chap router is configured, try using pap to validate all incoming The PPP session. If the remote device does not support pap, the router will attempt to use chap to verify PPP sessions. If the device doesnt Support for any protocol, and authentication will fail. And the PPP session will be
