address thus assigned by the remote interface. When accessing the Internet via an ISP,

Table 1-8
Configure an interface to negotiate IP address using PPP
Operation
Command
Configure an interface to negotiate IP
address using PPP.
ip address ppp-negotiate
Disable PPP negotiation.
undo ip address ppp-negotiate
By default, the system does not allow the interface to negotiate the IP address.
Caution:
z
Because PPP supports IP address negotiation, you can configure the interface to
negotiate the IP address only when PPP is encapsulated on the interface. When
PPP is disabled, the negotiated IP address will be deleted.
z
If the interface has an IP address, the original IP address is deleted after you
configure the interface to negotiate IP addresses.
z
After you configure the interface to negotiate IP addresses, you are not allowed to
assign an IP address for the interface. The negotiation can generate an IP address.
z
After you configure the interface to negotiate IP addresses twice, the IP address
generated by the first negotiation is deleted, and the IP address generated by the
second negotiation is used.
z
After the IP address generated by the negotiation is deleted, the interface has no IP
address.
2) Configure
server
If a firewall is functioning as server to assign IP address for a client, you can use the
following three methods to assign IP address for a PPP user:
Method1: Assign directly the specified IP address for the peer on the interface without
configuring an address pool.
