Configuring IP address negotiation
The device can perform IP address negotiation during IPCP negotiation. Through IP address negotiation,
one end can assign an IP address to the other.
IP address negotiation can be implemented in the following modes:
• The device operating as the client—This mode applies when a local interface uses PPP as its link
layer protocol but does not have an IP address, but the peer is configured with an IP address. In this
mode, the interface accepts an IP address allocated by its peer. This mode is used for situations
where a device accesses the Internet through an ISP, which assigns an IP address to the device.
• The device operating as the server—In this mode, you assign an IP address to the peer and
configure an IP address for the local device in interface view.
When IP address negotiation is enabled on a client, the server assigns an IP address to the client in the
following order:
• If the AAA server assigns an IP address to the client or has a specified address pool, the server
assigns that IP address or an IP address from the specified address pool to the client. The IP address
or address pool is configured on the AAA server instead of the PPP server.
• If an address pool is associated with the ISP domain used during client authentication, the server
assigns an IP address from the associated address pool to the client.
• If an IP address or address pool is specified for the client on the interface of the server, the server
assigns that IP address or an IP address from that address pool to the client.
To configure the device as the client:

is not enabled.
This command is mutually
exclusive with the ip address
command. For more information

Command Reference.
Configure the server to assign an IP address to a client by using the following methods:
• Method 1: Specify an IP address for the client on the server interface.
• Method 2: Specify an address pool on the server interface.
• Method 3: Use the address pool associated with the ISP domain.
