Configure IP
Address Pooling Point-to-point interfaces must be able to provide a remote node with
its IP address through the IP Control Protocol (IPCP) address negotia-
tion process. The IP address can be:
z Configured through the command lin
z Entered with an EXEC-level command
z Provided by TACACS+, DHCP, or from a locally administered
pool
IP address pooling consists of a pool of IP addresses from which an in-
coming interface can provide an IP address to a remote node through
the IP Control Protocol (IPCP) address negotiation process. It also en-
hances the flexibility of configuration by allowing multiple types of
pooling to be active simultaneously.
IP address pooling allows the configuration of a global default address
pooling mechanism, per-interface configuration of the mechanism,
and per-interface configuration of a specific address or pool name.
Peer Address Allocation
A peer IP address can be allocated to an interface through several
methods:
z Dialer map lookup. This method is used only if the peer requests
an IP address, if no other peer IP address has been assigned, and if
the interface is a member of a dialer group.
z PPP or SLIP EXEC command. An asynchronous dial-up user can
enter a peer IP address or host name when PPP or SLIP is invoked
from the command line. The address is used for the current session
and then discarded.
z IPCP negotiation. If the peer presents a peer IP address during
IPCP address negotiation and if no other peer address is assigned,
the presented address is acknowledged and used in the current ses-
sion.
z Chat script. The IP address in the dialer map command entry
that started the script is assigned to the interface and overrides any
previously assigned peer IP address.
z VTY/Protocol translation. Th translate command can defin
the peer IP address for a VTY (pseudo async interface).
