Interface Configuration Commands

Interface Configuration Commands

Purpose

These commands are used to configure an interface as either a DHCPv6 server or a DHCPv6 relay agent.

Commands

For information about...	Refer to page...

ipv6 dhcp server	24-10

ipv6 dhcp relay	24-11

ipv6 dhcp server

This command configures DHCPv6 server functionality on an interface.

Syntax

ipv6 dhcp server pool-name[rapid-commit} [preference pref]

no ipv6 dhcp server pool-name

Parameters

pool‐name	Specifies the pool containing stateless and/or prefix delegation
	parameters that should be used by the DHCPv6 server. Refer to
	“Address Pool Configuration Commands” on page 24‐6 for the
	commands to configure an address pool.

rapid‐commit	(Optional) Specify that the server should use the Rapid Commit option
	that allows for an abbreviated exchange between DHCPv6 client and
	server. Refer to RFC 3315 for more information.

preference pref	(Optional) Specifies the value of the server’s Preference option. This
	value, which can range from 0 to 4,294,967,295, is used by clients to
	determine preference among multiple DHCPv6 servers.

Defaults

By default, DHCPv6 functionality is disabled.

Mode

Router interface configuration: C3(su)‐>router(Config‐if(Vlan 1))#

Usage

Use this command to configure DHCPv6 server parameters when an interface will act as a DHCPv6 server. Address pools are configured using the commands described in section “Address Pool Configuration Commands” on page 24‐6.

An interface can be configured as either a DHCPv6 server or a DHCPv6 relay agent, but not both.

Use the no form of this command to remove DHCPv6 server functionality from an interface.
