Specify the ipv6-address as a destination address to which client messages are forwarded and which
enables DHCPv6 relay service on the interface. You can configure up to 16 relay destination
addresses on an interface. The outgoing-interface parameter is used when the destination relay
address is a link-local or multicast address. Specify the interface-type as ethernet interface, tunnel
interface, or VE interface. Specify the port-num as the port number.
Use the [no] version of the command to remove a DHCPv6 relay agent from the interface.
Enabling the interface-ID on the DHCPv6 relay agent messages
The interface-id parameter on the DHCPv6 relay forward message is used to identify the interface on
which the client message is received. By default, this parameter is included only when the client
message is received with the link-local source address.
To include the interface-id parameter on the DHCPv6 relay agent messages, enter the ipv6 dhcp-relay
include-options command at the interface level.
device(config-if-eth2/3)# ipv6 dhcp-relay include-options interface-id
Syntax: [no] ipv6 dhcp-relay include-options interface-id
Displaying DHCPv6 relay agent information
The show ipv6 dhcp-relay command displays the DHCPv6 relay agent information configured on the
device:
device(config)#show ipv6 dhcp-relay
Current DHCPv6 relay agent state: Enabled
DHCPv6 enabled interface(s): e 2/3
DHCPv6 Relay Agent Statistics:
Total DHCPv6 Packets, Received:0, Transmitted:0
Received DHCPv6 Packets: RELEASE:0,RELAY_FORWARD:0,RELAY_REPLY:0
OtherServertoClient:0,OtherClinettoServer:0
Syntax: show ipv6 dhcp-relay
Displaying the DHCPv6 Relay configured destinations
Enter the show ipv6 dhcp-relay destinations command to display information about the dhcpv6 relay
agent configured destinations.
device#show ipv6 dhcp-relay destinations

Displaying the DHCPv6 Relay configured destinations describes the fields from the output of show
ipv6 dhcp-relay destinations command.
