Configuration considerations
To configure the DHCPv6 server:
• Create a prefix pool.
To assign prefixes in the range of 2001:0410::/48 to 2001:0410:FFFF::/48, specify a prefix
2001:0410::/32 and specify the assigned prefix length as 48 in the pool.
• Create an address pool.
Specify a subnet where the IPv6 address of the server interface connecting the clients resides.
• Configure a static prefix binding, apply the prefix pool, and configure other configuration
parameters in the address pool.
• Enable the DHCPv6 server on the interface that connects the clients.
