Wanted to clarify two points:
1)
{15.0.0.0/8} is not accepted at all on (c d).
{10.0.0.0/8} is not accepted at all on (a b).

(You used "15 is best a-b" which does not explicitly say it is not
accepted on c-d).

2)
If there was a third link (e, f) for which there is no interas-in
line. The policies for that link is:
	networks in AS2 setminus {15.0.0.0/8} setminus {10.0.0.0/8}

Just wanted to make sure. I think this complicated interaction of
as-in and interas-in will be confused by a lot of people. Luckily only
few and hopefully more knowledgable people will actually specify
these.
