Dynamic Host Configuration Protocol Dhcp Server | Paradyne 6302

3. Configuring the DSL Router

Dynamic Host Configuration Protocol (DHCP) Server

The router provides a DHCP Server feature, as specified in RFC 2131, Dynamic Host Configuration Protocol, and RFC 2132, DHCP Option and BOOTP Vendor Extensions. DHCP is the protocol used for automatic IP address assignment.

DHCP setup considerations:

The range of IP addresses to be used by the DHCP server must be configured. The maximum number of clients is 256.

The DHCP server is not activated until one IP address and subnet mask are assigned to the Ethernet interface and routing is enabled.

The DHCP server must be enabled, and the DHCP server and DHCP relay functions cannot be enabled at the same time.

When the DHCP IP address range is changed, all binding entries, automatically added routes, and ARP Table entries for the clients configured with the old address range are removed.

When the DHCP Server is enabled, there can be only one IP address configured for the service domain (Ethernet interface).

The IP address for the next hop router provided to the hosts in the DHCP reply must be configured.

The subnet mask can be configured along with the IP address range (optional).

The DHCP server domain name can be configured (optional).

The Domain Name Server (DNS) IP address can be configured (optional).

A minimum and maximum lease time setting can be configured.

For additional information, refer to Chapter 4, DSL Router Configuration

Examples.
