Never mind

Thanks all

I've never seen an IPv6 RFC specify to put the VLAN number in the link-local address.
Thus this must be an (odd) choice made by some implementation. Perhaps the implementation somehow requires that all the link-local addresses for all its (sub)interfaces be unique, even though the RFCs assume that the implementation should be able to deal with multiple interfaces with same same link-local address.

And unless you are on only certain particular devices (e.g. L3 switches)
then the end device won't necessarily have any relevant clue what VLAN it's
on.
I have never seen/heard of an RFC for it either and would certainly wonder
"WHY?".
