Configure IP Address Pooling

2.Enable compression.

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 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:

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 interface and overrides any previously assigned peer IP address.

zVTY/Protocol translation. Th translate command can defin the peer IP address for a VTY (pseudo async interface).
