Parameter
None
Description
Using the ip address ppp-negotiate command, you can allow IP address be
assigned through negotiation at the interface. Using the undo ip address
ppp-negotiate command, you can disable this function.
By default, no interface ip address negotiation is allowed.
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.
Example
