Description As PPP supports IP address negotiation, only when the interface is encapsulated with
the link-layer protocol PPP, can the IP address negotiation at this interface be
configured.
Normally, it is not necessary to configure IP address negotiation. Only in some special
circumstances such as accessing Internet through the ISP, the IP addresses of the
interface that is connected with the ISP are allocated by the ISP through negotiation.
When IP address negotiation for the interface is configured, it is not necessary to
configure the IP address manually for this interface.
