ARP Configuration Commands 401
while configuring the remote address command on the peer router), so that the
local interface can accept the IP address originated from PPP negotiation. This IP
address is assigned by the opposite end. This configuration is mainly used to
obtain IP address assigned by ISP when accessing Internet via ISP.
For the related command, see ip address ppp-negotiate.
Example
The serial interface encapsulated with PPP assigns an IP address 10.0.0.1 for the
peer.

used for LAN only, WAN address resolution is accomplished in a different way, for
