Applying a DHCPv6 address pool to a VPN instance
About DHCPv6 address pool application 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.
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.
An MCE acting as the DHCP server can assign IP addresses not only to clients on public networks, but also to clients on private networks. The IP address ranges of public and private networks or those of private networks on the DHCP server cannot overlap. For more information about MCE, see MPLS Configuration Guide.
