Configuration guidelines
Follow these guidelines when you configure the DHCPv6 relay agent:
Before you configure the DHCPv6 relay agent, enable IPv6 by using the ipv6 command in system view.
Executing the ipv6 dhcp relay server-address command repeatedly can specify multiple DHCPv6 servers. 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 must 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.
HP does not recommend enabling the DHCPv6 relay agent and DHCPv6 client on the same interface
