| What should we do?
The rational solution is that when the PPPoE implementations are enhanced
to support IPv6 (since it is PPP, it knows about address negotiation, and
hence needs to be updated), then simultaneously update the implementation
to be able to handle a more sensible MTU for IPv6 .. this has to be a much
more trivial change than supporting IPv6 in the first place.
But also, since any PPP can have almost any MTU configured into it, I would
assume that IPv6 over PPP will be (or has already) defining some link level
fragmentation scheme, as required for any link level for IPv6 with an MTU
less than 1280. Since PPPoE is more or less just PPP, it should be able
to use the same mechanisms, if it finds its link MTU happens to have been
set < 1280.
The only other option for IPv6 over PPP would be to define that the minimum
MTU for a PPP link carrying IPv6 is 1280 - in which case PPPoE will just
have to follow along.
