ipv6 dhcp relay

Example

This example configures routing interface VLAN 7 to be a DHCPv6 server, using the address pool named PoolA.

C3(su)->router(Config)# interface vlan 7

C3(su)->router(Config-if(Vlan 7))# ipv6 dhcp server PoolA

ipv6 dhcp relay

This command configures an interface for DHCPv6 relay agent functionality.

Syntax

ipv6 dhcp relay {destination dest-addrinterface intf interface intf} [remote-id {duid-ifid user-defined-string}]

no ipv6 dhcp relay {destination dest-addrinterface intf interface intf}

Parameters

destination dest‐addr	Specifies the IPv6 address of a DHCPv6 relay server. This IPv6 address
	can be a global address, a multicast address, or a link‐local address.
	If the address is a multicast or link‐local address, then you must specify
	the interface to be used to contact the relay server with the interface
	parameter.

interface intf	Specifies the interface to be used to contact the relay server. The
	interface is identified by port type.unit number.port number. For
	example, ge.3.1.
	If destination dest‐addr is not specified, then an interface must be
	specified and the DHCPV6‐ALL‐AGENTS multicast address (FF02::1:2)
	is used to relay DHCPv6 messages to the relay server.

remote‐id {duid‐ifid	(Optional) Specifies that the Relay Agent Information Option
user‐defined‐string}	Remote‐ID sub‐option is to be added to relayed messages.
	Specifying duid‐ifid causes the remote ID to be derived from the relay
	agent’s DUID and the relay interface number. Alternatively, you can
	specify the remote ID as a user‐defined‐string of alpha‐numeric
	characters. Refer to RFC 3046 and RFC 4649 for more information about
	the Remote‐ID option.

Defaults

If remote‐id is not specified, the Relay Agent Information Option Remote‐ID sub‐option is not added to relayed messages.

Mode

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

Usage

Use this command to configure a routing interface as a DHCPv6 relay agent.

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 relay agent functionality from an interface.
