Hi Toerless,

Picking up on this thread, little late, sorry..

> I liked Pierre's bitstring in IPv6 addr, i just felt it was too short to be useful.

It would disagree, it’s about half the size of what we consider to be the standard interoperable mask of 256. We have defined the Set approach to overcome BM length limitations, at the expense of more copies sent by the ingress. Pun intended, BIER-TE is much more restricted to be useful 😉

Thx,

Ice.
