ISP, the IP address is usually allocated by the peer server. The PPP packet must
be encapsulated and the IP address negotiated attribute must be configured on
the interface so that the local interface accepts the IP address allocated by the
peer end through the PPP negotiation.
IP unnumbered

can borrow the IP address of the interface that is configured with an IP address
to save the IP address resource.
