Applying A Dhcpv6 Address Pool To A Vpn Instance; Configuring Dhcpv6 Logging On The Dhcpv6 Server - HP FlexNetwork MSR2003 Configuration Manual

Step
1. Enter system view.
2. Create an address pool and
enter its view.
3. Advertise the subnet assigned
to DHCPv6 clients.
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.
To apply a DHCPv6 address pool to a VPN instance:
Step
1. Enter system view.
2. Create an address pool and
enter its view.
3. Apply the address pool to a
VPN instance.
Configuring DHCPv6 logging on the DHCPv6
server
The DHCPv6 logging feature enables the DHCPv6 server to generate DHCPv6 logs and send them
to the information center. For information about the log destination and output rule configuration in
the information center, see Network Management and Monitoring Configuration Guide.
Disable this feature when the log generation affects the device performance or reduces the address
and prefix allocation efficiency. For example, this situation might occur when a large number of
clients frequently come online or go offline.
