Configuring Ccna Dhcp On A Cisco Router Overview Part 1
RFC 2131, DHCP offers IP address and other parameters to IP hosts.
DHCP is a server/client setup were DHCP Clients are given network addresses and other configuration parameters to dynamically configured hosts.
DHCP supports three mechanisms for IP address allocation:
• Static/Automatic allocation — DHCP Server leases a permanent IP address to a DHCP client.
• Dynamic allocation—DHCP Server leases an IP address to a DHCP client for a limited period of time or until the DHCP client gives up the IP address information
• Reserved / Manual allocation—Here the network administrator manually reserves and assigns an IP address to a DHCP client and the Server DHCP conveys the assigned address to the DHCP client.
