About DHCPv6 Relay

SonicOS supports DHCPv6 Relay. A DHCP relay agent is a node that acts as an intermediary to deliver DHCP messages between clients and server, and is on the same link as the client. A DHCPv6 relay agent is used to relay messages between the client and the server when they are not on the same IPv6 link. The DHCPv6 relay agent operation is transparent to the client.

In SonicOS, supported destination addresses can be global addresses or link-local addresses, but not multicast addresses.

DHCPv6 relay can be enabled on both physical and virtual interfaces. DHCPv6 is a built-in application in IP Helper protocols.
