*What netmask should the client use for the received address* in this case?
When we tested this, it used /128 which is the only sane behaviour I can see.
The only obvious alternatives I can think of are /64 and /128, since the IA_NA address doesn't include a prefix length. Can anybody point me to RFCs which describe this?
I think the RFC I quoted already says this, if you don't get an on-link prefix, you're not allowed to make up an on-link prefix. If you get an address, you get that single address, nothing else.
Thus the behaviour I've seen is correct, you end up with a /128 pointing to yourself and a default route pointing to the router LL address, nothing else.
