Define DHCP as the Global Default Mechanism
The Dynamic Host Configuration Protocol (DHCP) specifies these
components:
zA DHCP server. A host-based DHCP serv er c on fi gured to accept
and process requests for tempo rary IP addresses.
zA DHCP proxy-client. An access server configured to arbitrate
DHCP calls between the DHCP server and the DHCP client. T h
DHCP client-proxy feature manages a pool of IP addresses avail-
able to dial-in clients without a known IP address.
In global configuration mode, enable DHCP as the global default
mechanism:
1. Specify DHCP client-proxy as the global default mechanism.
ip address-pool dhcp-proxy-client
2. (Optional) Specify the IP address of a DHCP server for the proxy
client to use.
ip dhcp-server [
ip-address
|
name
]
You can provide up to ten DHCP servers for the proxy-client (the
router or access server) to use. DHCP servers provid e temporary IP ad-
dresses.
Define Local Address Pooling as the Global Default Mechanism
In global configuration mode, define local pooling as the global de-
fault mechanism:
1. Specify local pooling as the global default mechanism.
ip address-pool local
2. Create one or more local IP address pools.
ip local pool {default |
poolname
}
low-ip-address
[
high-ip-address]
If no other pool is defined, the local pool called default is used.
