R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

693
Upon receiving a request from a DHCPv6 client, the interface that operates as a DHCPv6 relay agent
encapsulates the request into a Relay-forward message and forwards the message to the specified
DHCPv6 server, which then assigns an IPv6 address and other configuration parameters to the DHCPv6
client.
Executing the ipv6 dhcp relay server-address command repeatedly can specify multiple DHCPv6 servers,
and up to eight DHCP servers can be specified for an interface. After receiving requests from DHCPv6
clients, the DHCPv6 relay agent forwards the requests to all the specified DHCPv6 servers.
If the DHCPv6 server address is a link-local address or link-scoped multicast address on the local link, you
must specify an outgoing interface. If no outgoing interface is specified, DHCPv6 packets may fail to be
forwarded to the DHCPv6 server.
After you remove all the specified DHCPv6 servers from an interface with the undo ipv6 dhcp relay
server-address command, DHCPv6 relay agent is disabled on the interface.
An interface cannot serve as a DHCPv6 client and DHCPv6 relay agent at the same time.
