system-view [Sysname] ipv6 dhcp dscp 30 ipv6 dhcp relay server-address Syntax ipv6 dhcp relay server-address ipv6-address [ interface interface-type interface-number ] View undo ipv6 dhcp relay server-address ipv6-address [ interface interface-type interface-number ] Interface view Default level 2: System level Parameters ipv6-address: Specifies the IPv6 address of the DHCPv6 server. interface interface-type interface-number: Specifies an outgoing interface for DHCPv6 packets. Description Use ipv6 dhcp relay server-address to enable DHCPv6 relay agent on the interface and specify a DHCPv6 server. Use undo ipv6 dhcp relay server-address to remove the DHCPv6 server from the interface. By default, DHCPv6 relay agent is disabled and no DHCPv6 server is specified on the interface. 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. Related commands: display ipv6 dhcp relay server-address.
