Saudi Telecom sending route with invalid attributes 212.118.142.0/24

Sat Sep 10 22:26:14 UTC 2011

Looks like the RIS collectors are seeing it originating mostly from
STC and KACST ASNs:
<http://stat.ripe.net/212.118.142.0/24>

Some of the "show ip bgp" reports on that screen are also showing
AS8866 "BTC-AS Bulgarian Telecommunication Company".  Not sure what's
up with that.
