DHCPv6 Commands

Syntax

ipv6 dhcp relay {destination relay-address [interface vlan vlan-id] | interface vlan vlan-
id}[remote-id {duid-ifid | user-defined-string}]

destination—Keyword that sets the relay server IPv6 address.

relay-address—An IPv6 address of a DHCPv6 relay server.

interface—Sets the relay server interface.

vlan-id—A valid VLAN ID.

[remote-id {duid-ifid|user-defined-string}]—The Relay Agent Information Option
“remote ID” sub-option to be added to relayed messages. This can either be the special
keyword duid-ifid, which causes the “remote ID” to be derived from the DHCPv6 server
DUID and the relay interface number, or it can be specified as a user-defined string.

Default Configuration

This command has no default configuration.

Command Mode

Interface Configuration (VLAN, Tunnel) mode

User Guidelines

If relay-address is an IPv6 global address, then relay-interface is not required. If relay-address is
a link-local or multicast address, then relay-interface is required. Finally, a value for relay-
address is not specified, then a value for relay-interface must be specified and the DHCPV6-
ALLAGENTS multicast address (i.e. FF02::1:2) is used to relay DHCPv6 messages to the
relay server.

Example

The following example configures VLAN 15 for DHCPv6 relay functionality.

console(config)#interface vlan 15

console(config-if-vlan15)#ipv6 dhcp relay destination 2020:1::1

ipv6 dhcp relay-agent-info-opt

Use ipv6 dhcp relay-agent-info-opt command in Global Configuration mode to configure a
number to represent the DHCPv6 Relay Agent Information Option. The DHCPv6 Relay Agent
Information Option allows for various sub-options to be attached to messages that are being
relayed by the local router to a relay server. The relay server may in turn use this information in
determining an address to assign to a DHCPv6 client.
