Parameters
interface: Specifies the interface name mode. This mode pads the Interface-ID option in ASCII code
with the interface name and VLAN ID of the interface.

Parameters
ipv6-address: Specifies the IPv6 address of a DHCPv6 server.
interface interface-type interface-number: Specifies an output interface through which the relay
agent forwards the DHCPv6 requests to the DHCPv6 server. If you do not specify an output interface,
the relay agent looks up the routing table for an output interface.
Usage guidelines
Upon receiving a request from a DHCPv6 client, the interface encapsulates the request into a
Relay-forward message and forwards the message to the specified DHCPv6 server.
You can specify a maximum of eight DHCPv6 servers on an interface. The DHCPv6 relay agent
forwards DHCP requests to all the specified DHCPv6 servers.
If the DHCPv6 server address is a link-local address or multicast address, you must specify an
output interface. If you do not specify an output interface, DHCPv6 packets might fail to reach the
DHCPv6 server.
