Configuration procedure

1. Configure Router A:

# Configure an IP address to be assigned to the peer interface on Serial 2/1/0.

<RouterA> system-view

[RouterA] interface serial 2/1/0

[RouterA-Serial2/1/0] remote address 200.1.1.10

# Configure an IP address for Serial 2/1/0.

[RouterA-Serial2/1/0] ip address 200.1.1.1 16

2. Configure Router B:

# Enable IP address negotiation on Serial 2/1/0.

<RouterB> system-view

[RouterB] interface serial 2/1/0

[RouterB-Serial2/1/0] ip address ppp-negotiate

3. Verify the configuration:

# After the configuration is complete, display summary information about Serial 2/1/0 on Router

[RouterB-Serial2/1/0] display interface serial 2/1/0 brief

Brief information on interface(s) under route mode:

Link: ADM - administratively down; Stby - standby

Protocol: (s) - spoofing

Interface Link Protocol Main IP Description

S2/1/0 UP UP 200.1.1.10

The output shows Serial 2/1/0 obtains IP address 200.1.1.10 through PPP negotiation.

# Ping Serial 2/1/0 of Router A from Router B.

[RouterB-Serial2/1/0] ping 200.1.1.1
