PPP IP address negotiation configuration example
Network requirements
As shown in Figure 7, configure Router A to allocate an IP address for Serial 2/0 of Router B through
PPP negotiation.
Figure 7 Network diagram
Configuration procedure
1. Configure Router A:
# Configure a local IP address pool.
<RouterA> system-view
[RouterA] ip pool 1 200.1.1.10 200.1.1.20
# Configure the IP address of Serial 2/0.
[RouterA] interface serial 2/0
[RouterA-Serial2/0] ip address 200.1.1.1 16
# Allocate an IP address to the remote port (Serial 2/0 of Router B) from the IP address pool.
[RouterA-Serial2/0] remote address pool 1
2. Configure Router B:
# Enable IP address negotiation on Serial 2/0.
<RouterB> system-view
[RouterB] interface serial 2/0
[RouterB-Serial2/0] ip address ppp-negotiate
