Parameters
ipv6-address: IPv6 address of the DHCPv6 server.
interface interface-type interface-number: Specifies an output interface for DHCPv6 packets.
Usage guidelines
Upon receiving a request from a DHCPv6 client, the interface that operates as a DHCPv6 relay agent
encapsulates the request into a Relay-forward message and forwards the message to the specified
DHCPv6 server, which then assigns an IPv6 address and other configuration parameters to the DHCPv6
client.
You can specify up to eight DHCPv6 servers for an interface. After receiving requests from DHCPv6
clients, the DHCPv6 relay agent forwards the requests to all specified DHCPv6 servers.
If the DHCPv6 server address is a link-local address or link-scoped multicast address on the local link,
specify an output interface. If you do not specify any output interface, DHCPv6 packets might fail to be
forwarded to the DHCPv6 server.
After you remove all specified DHCPv6 servers from an interface with the undo ipv6 dhcp relay
server-address command, DHCPv6 relay agent is disabled on the interface.
An interface cannot serve as a DHCPv6 client and DHCPv6 relay agent at the same time.
Examples
# Enable DHCPv6 relay agent on GigabitEthernet 3/1/1 and specify the DHCPv6 server address as
2 0 01:1: : 3.
