2. Enable IP address negotiation on Serial 2/1/0 of Router B.
<RouterB> system-view
[RouterB] interface serial 2/1/0
[RouterB-Serial2/1/0] ip address ppp-negotiate
3. Verify the configuration:
# Display summary information about Serial 2/1/0 on Router B.
[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 that Serial 2/1/0 has obtained IP address 200.1.1.10 through PPP negotiation.
# Verify that Router B can ping Serial 2/1/0 of Router A.

Using the PPP address pool associated with an ISP domain
Network requirements
As shown in Figure 8, configure Router A to allocate an IP address from the PPP address pool associated
with the ISP domain to Serial 2/1/0 of Router B through PPP negotiation.
