Verifying the configuration
After the preceding configuration is complete, the clients in subnets 1::1:0:0:0/96 and 1::2:0:0:0/96
can obtain IPv6 addresses and other configuration parameters from the DHCPv6 server (Switch A). You
can use the display ipv6 dhcp server ip-in-use command to display IPv6 addresses assigned to the
DHCPv6 clients.
