Usage guidelines

A DHCPv6 client can obtain an IPv6 prefix through DHCPv6 and use the IPv6 prefix for IPv6 address assignment in a downstream network. If the IPv6 prefix is in a different subnet than the IPv6 address of the DHCPv6 client's upstream interface, the downstream network cannot access the external network. You can use this command to configure the DHCPv6 server or DHCPv6 relay agent, whichever is on the same link as the DHCPv6 client, to advertise the IPv6 prefix.

To use this command on the DHCPv6 relay agent, you must enable the DHCPv6 relay agent to record DHCPv6 relay entries first.
