4. Address from an EXEC-level PPP or SLIP command or from a
chat script
5. Configured address from the peer default ip address
command or add ress from the protocol translate command
6. Peer provided ad d re ss f ro m IPCP neg o ti ati on (not ac ce pt ed unless
no other address exists)
Interfaces Affected
IP address pooling is available on all asynchronous serial, synchro
nous serial, ISDN BRI, and ISDN PRI interfac es r u nn ing the Point-to-
Point Protocol (PPP) or Serial Line Internet Protocol (SLIP).
Choose the IP Address Assignment Method
IP address pooling allows configuration of a global default address
pooling mechanism, per-interface configuration of the mechanism,
and per-interface configur ation of a specific address or pool name.
You can define the type of IP address pool i ng mec hanism used on
router interfaces by completing t hese actions:
zDefine the Global Default Mechanism
zConfigure Per-Interface IP Addres s Assignment
Define the Global Default Mechanism
The Global Default Mechanism applies to all point-to-point interfaces
(asynchronous, synchronous, ISDN BRI , ISDN PRI, and dialer inter-
faces) that support PPP encapsulation and that have not otherwise been
configured for IP address pooling. You can defi ne the Global Default
Mechanism to be either DHCP or local address pooling.
To configure the global default mechanism for IP address pooling, per-
form one of these tasks:
zDefine DHCP as the Global Defau lt M echanism
zDefine Local Address Pooling as the Global Default Mechanism
After you have defined a global default mechanism, you can disable it
on a specific interface by configuring the interface for some other
pooling mechanism. You can define a local pool other than the default
pool for the interface, or you can configure th e interface with a specifi
IP address to be used for dial-in peers.
