303
Parameters
vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to
31 characters. If you do not specify a VPN instance, the DHCPv6 address pool belongs to the public
network.
Usage guidelines
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 specified VPN instance.
The DHCPv6 server identifies the VPN instance to which a DHCPv6 client belongs according to 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.
Examples
# Apply DHCPv6 address pool 0 to the VPN instance abc.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 0
[Sysname-dhcp6-pool-0] vpn-instance abc
