# Enable PPP encapsulation on Serial 2/0/1.

[RouterA] interface serial 2/0/1

[RouterA-Serial2/0/1] link-protocol ppp

# Set the authentication mode to PAP.

[RouterA-Serial2/0/1] ppp authentication-mode pap domain system

# Assign an IP address to Serial 2/0/1.

2. Configure Router B:

# Enable PPP encapsulation on Serial 2/0/1.

<RouterB> system-view

[RouterB] interface serial 2/0/1

[RouterB-Serial2/0/1] link-protocol ppp

# Configure the PAP username and password sent from Router B to Router A when Router B is

authenticated by Router A using PAP.

[RouterB-Serial2/0/1] ppp pap local-user userb password simple passb

# Assign an IP address to Serial 2/0/1 of Router B.

[RouterB-Serial2/0/1] ip address 200.1.1.2 16

3. Verify the configuration:

Use the display interface serial command to display information about Serial 2/0/1 of Router B.

The physical layer status and link layer status of the interface are both up, and the states of LCP and

IPCP are both Opened, indicating PPP negotiation is successful. Router A and Router B can ping

each other.
