We periodically see UUNET suddenly leak large numbers of what I can only assume are interior routes, to quite a few peers, and then rapidly withdraw them: +---------------------+------+-------------------+------+--------+ | time | type | prefix | mask | aspath | +---------------------+------+-------------------+------+--------+ | 2002-04-24 03:20:50 | A | 208.254.255.0 | 24 | 1 701 | | 2002-04-24 03:22:14 | A | 208.254.255.0 | 24 | 1 701 | | 2002-04-24 03:22:36 | W | 208.254.255.0 | 24 | NULL | +---------------------+------+-------------------+------+--------+ ... now you see it, now you don't. A check with routeviews shows that we're not the only one seeing such things. For instance, from AT&T's perspective: +---------------------+--------+------+---------------+------+----------+ | time | src_as | type | prefix | mask | aspath | +---------------------+--------+------+---------------+------+----------+ | 2002-04-24 03:20:39 | 7018 | A | 208.254.255.0 | 24 | 7018 701 | | 2002-04-24 03:21:06 | 7018 | A | 208.254.255.0 | 24 | 7018 701 | | 2002-04-24 03:22:05 | 7018 | A | 208.254.255.0 | 24 | 7018 701 | | 2002-04-24 03:22:35 | 7018 | W | 208.254.255.0 | 24 | NULL | +---------------------+--------+------+---------------+------+----------+ These seem to happen about once a month or so, typically at odd hours. Is this a goof up, or some strange leakage during filter reconfiguration? Anyone from UUNET care to clue me in?
