Applying a DHCPv6 address pool to a VPN instance
If a DHCPv6 address pool is applied to a VPN instance, the DHCPv6 server assigns IPv6 addresses in this address pool to clients in the VPN instance. Addresses in this address pool will not be assigned to clients on the public network.
The DHCPv6 server can obtain the VPN instance to which a DHCPv6 client belongs from the following information:
The client's VPN information stored in authentication modules, such as IPoE.
The VPN information of the DHCPv6 server's interface that receives DHCPv6 packets from the client.
The VPN information from authentication modules takes priority over the VPN information of the receiving interface.
