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:
zConfigured through the command lin
zEntered with an EXEC-level command
zProvided by TACACS+, DHCP, or from a locally administered
pool
IP address pooling consists of a pool of IP addres ses 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 o f a global d efault address
pooling mechanism, per-interface configuration of the mechanism,
and per-interface configur ation of a specific address or pool name.
Peer Address Allocation
A peer IP address can be allocated to an interface through several
methods:
zDialer 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.
zPPP 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.
zIPCP 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.
zChat script. The IP address in the dialer map command entry
that started the script is assigned to the in terface and o verrides any
previously assigned peer IP address.
zVTY/Protocol translation. Th translate command can defin
the peer IP address for a VTY (pseudo async inte rface).
