This should not be true anymore. When looking into ORR I raised this
concern to JNPR, because in ORR you essentially need group per
neighbour to have unique view per neighbour, and I was worried about
RIB scale exploding.
However JNPR said that they do not anymore create unique copy of RIB
just because there is new group. I didn't manage to figure out which
release it has come and how it works, but supposedly it's before ORR,
and ORR came in 15.1F4 so at least that and newer releases should be
memory-friendly to large amount of groups.
