Configuration procedure
1) Configure Router A.
# Create a user account for Router B.
<RouterA> system-view
[RouterA] local-user userb
# Set a password for the user account.
[RouterA-luser-userb] password simple passb
# Set the service type of the user account to PPP.
[RouterA-luser-userb] service-type ppp
[RouterA-luser-userb] quit
[RouterA] interface serial 2/0/1
# Enable PPP encapsulation for 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.
[RouterA-Serial2/0/1] ip address 200.1.1.1 16
[RouterA-Serial2/0/1] quit
# Create an ISP domain named system.
[RouterA] domain system
# Configure the users in the domain to use the local authentication scheme.
[RouterA-isp-system] authentication ppp local
2) Configure Router B.
# Enable PPP encapsulation for 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 configurations
Use the display interface 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 that PPP negotiation is successful. Router A and Router B can ping each other.
