Hi:

For DHCPv6, we either need to explicitly state that the server MUST copy and add the DHCPv6 Relay Agent Source Port Option when constructing the Relay-Reply chain from the Relay-Forw(s) or the relay must include the ERO option (see RFC 4994) to request that the server echo back this option. For DHCPv4, the entire option 82 is sent back to the relay; but for DHCPv6, only limited relay options are added into the Relay-Reply (just the Interface-Id option is copied per RFC 3315).
