Configuration considerations
Configure the DHCPv6 server as follows:
• Enable IPv6 and DHCPv6 server.
• Create a prefix pool containing prefix 2001:0410::/32 with the length of the assigned prefix being
48, so that the server assigns clients the prefixes ranging 2001:0410::/48 to
2001:0410:FFFF::/48.
• Create an address pool. Configure a static prefix in the address pool and have the prefix pool
referenced by the address pool. Configure other configuration parameters.
• Apply the address pool to the interface through which the server is connected to the clients.
• Enable the DHCPv6 server on the interface that connects to the clients and apply the address pool
to the interface.
