You are right, both variants (separate radv protocols or rdnns blocks
inside interface blocks) should work. Also note that 'rdnss local' option
only says that protocol-wide rdnss block should not be used for that
interface. If you have only interface-specific rdnss blocks, that option
is not necessary (interface-specific blocks are used always).
