Configuring ODAPs to Obtain Subnets Through IPCP Negotiation
Example 10-8 creates a DHCP address pool named my_pool, configures the pool as an on-demand
address pool using IPCP as the subnet allocation protocol, and configures the Ethernet0 interface to
automatically obtain its IP address from the my_pool address pool.
Example 10-8 Enabling ODAPs to Obtain Subnets Through IPCP Negotiation
!
ip dhcp pool my_pool
import all
origin ipcp
!
interface Ethernet0
ip address pool my_pool
ip verify unicast reverse-path
shutdown
