The link-address field in the Relay-Forw is usually used for this and no link-selection option is needed.

The reason v4 needs this is that giaddr is both the relay agent's address AND the default link-selection. With DHCPv6, there is no overloading - the Relay Agent address is obtained from the IPv6 header (source address) the link-selection is the link-address field in the Relay-Forw.

Subject: [dhcwg] Regarding DhcpV6 alternatives to dhcpv4 option 118 and dhcp option 82 sub-option 5

Hi All
I would like to know whether there are any link selection options for dhcpv6 like option 118 for dhcpv4 client and Option 82 Sub-option 5 for DHCP V4 relay agents.
Regards
Vivek
