=> you confused interface which says this subnet is for the link directly
connected to the interface, and interface-id which says the link is behind
a relay which adds this opaque interface-id RAI suboption to packets
which comes from clients on the link.

Of course you can be in both cases at the same time. Remember I wrote
after recommending the interface clause in subnet that I assume
there is no relay.

=> no, a vlan should map to a subnet (link in IPv6 terms).

PS: the interfaces-config global clause specifies interfaces Kea is
listen on. In ISC DHCP it is a command line parameter.
