Configuration guidelines

You can use the ipv6 dhcp relay server-address command to specify a maximum of eight DHCPv6
•
servers on the DHCP relay agent interface. The DHCPv6 relay agent forwards DHCP requests to all
the specified DHCPv6 servers.
If a specific DHCPv6 server address is a link-local address or multicast address, you must specify an
•
outgoing interface by using the interface keyword in the ipv6 dhcp relay server-address command.
Otherwise, DHCPv6 packets might fail to reach the DHCPv6 server.
• 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.
4. Specify a DHCPv6 server.
5. Set the DSCP value for
DHCPv6 packets sent by the
DHCPv6 relay agent.

N/A
By default, the DHCPv6 relay agent is
disabled on the interface.
By default, no DHCPv6 server is
specified.
By default, the DSCP value for
DHCPv6 packets sent by the DHCPv6
relay agent is 56.
The DSCP value of a packet specifies
the priority level of the packet and
affects the transmission priority of the
packet.
