Enabling the DHCPv6 relay agent on an interface

As a best practice, do not enable DHCPv6 relay agent and DHCPv6 client on the same interface.

1. Enter system view.

   system-view

2. Enter interface view.

   interface interface-type interface-number

3. Enable DHCPv6 relay agent on the interface.

   ipv6 dhcp select relay

   By default, the DHCPv6 relay agent is disabled on the interface.
