Refer to the exhibit. What should be done to allow PC-A to receive an IPv6 address from the DHCPv6 server?
- Add the ipv6 dhcp relay command to interface Fa0/0.
- Change the ipv6 nd managed-config-flag command to ipv6 nd other-config-flag.
- Configure the ipv6 nd managed-config-flag command on interface Fa0/1.
- Add the IPv6 address 2001:DB8:1234:5678::10/64 to the interface configuration of the DHCPv6 server.
Explanation: Client DHCPv6 messages are sent to a multicast address with link-local scope, which means that the messages will not be forwarded by routers. Because the client and server are on different subnets on different interfaces, the message will not reach the server. The router can be configured to relay the DHCPv6 messages from the client to the server by configuring the ipv6 dhcp relay command on the interface that is connected to the client.
