DHCPv6 Commands

78-21075-01 Command Line Interface Reference Guide

ipv6 dhcp relay destination [

no ipv6 dhcp relay destination [

ipv6-address—Relay destination address. The following types of relay

destination addresses exist:

Link-local unicast. A user must specify an output interface for this kind of

Global unicast IPv6 address. An output interface cannot be specified for

this kind of address.

This argument must be in the form documented in RFC 4291 where the

address is specified in hexadecimal using 16-bit values between colons.

If the argument is not configured then the well-known link-local Multicast

address All_DHCP_Relay_Agents_and_Servers (FF02::1:2) is defined.

interface-id—Specifies the output interface for a destination. If this

argument is configured, client messages are forwarded to the destination

address through the link to which the output interface is connected.

Default Configuration

The relay function is disabled, and there is no relay destination on an interface.

Command Mode

Interface configuration (config-if)

User Guidelines

This command specifies a destination address to which client messages are

forwarded, and it enables DHCP for IPv6 relay service on the interface.

DHCPv6 Relay inserts the Interface-id option if an IPv6 global address is not

defined on the interface on which the relay is running. The Interface-id field of the

option is the interface name (a value of the ifName field of the ifTable) on which the

relay is running.

When relay service is running on an interface, a DHCP for IPv6 message received

on that interface will be forwarded to all configured relay destinations configured

per the interface and globally.
