When you configure/build a PPP connection between two locations, IP
addresses are exchanged as part of the IPCP phase, if I recall
correctly. A router will add its neighbor's IP address as connected to
the global route table unless the 'no peer neighbor-route' command is
used in the PPP interface configuration.
