Configuration Procedure
Follow these steps to configure the DHCPv6 relay agent:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view
interface interface-type
interface-number
—
Enable DHCPv6 relay agent on the
interface and specify a DHCPv6
server
ipv6 dhcp relay server-address
ipv6-address [ interface
interface-type interface-number ]
Required
By default, DHCPv6 relay
agent is disabled and no
DHCPv6 server is specified on
the interface.
NOTE:
•
Executing the ipv6 dhcp relay server-address command repeatedly can specify multiple DHCPv6
servers, and up to eight DHCPv6 servers can be specified 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 need to specify an outgoing interface 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.
• An interface cannot serve as a DHCPv6 relay agent and DHCPv6 server at the same time.
• It is not recommended that you enable the DHCPv6 relay agent and DHCPv6 client on the same
interface.
