within the Relay Message option of a Relay-reply message. The DHCPv6 server then sends the
Relay-reply message to the DHCPv6 relay agent.
The DHCPv6 relay agent obtains the reply from the Relay-reply message and sends the reply to the
4.
DHCPv6 client.
Then the DHCPv6 client uses the IPv6 address and other network parameters assigned by the DHCPv6
server to perform network configuration.

Configuration prerequisites

Before you configure the DHCPv6 relay agent, enable IPv6 by using the ipv6 command in system view.

Configuration guidelines

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 the specified DHCPv6 servers.
If the DHCPv6 server address is a link-local address or link-scoped multicast address on the local
•
link, you must specify an outgoing interface by using the interface keyword in the ipv6 dhcp relay
server-address command. Otherwise, DHCPv6 packets may fail to be forwarded to the DHCPv6
server.
After you remove all the specified DHCPv6 servers from an interface with the undo ipv6 dhcp relay
•
server-address command, DHCPv6 relay agent is disabled on the interface.
• Do not enable the DHCPv6 relay agent and DHCPv6 client on the same interface.

Configuration procedure

To configure the DHCPv6 relay agent:
Step
1. Enter system view.
2. Enter interface view.
3. Enable DHCPv6 relay agent
on the interface and specify a
DHCPv6 server.
