I've changed jobs and been off the NANOG list for some time, so please
excuse the question.
I know some providers (such as SPRINT) filter BGP routing announcements
based on minimum announcement size. The questions are:
1) Who all has such policies?
2) What are the specific sizes and address blocks being filtered?
3) Do they affect "portable" (provider independent) and "non-portable
(provider supplied) addressing in the same way.
Thanks.
