RE: The Cidr Report

Hank and Warren are right on.   I have seen several ISPs (one of which has been around a long time) who don't even understand the basics of CIDR routing or why they should aggregate their announcements.   This same group are the ones who are not subscribed to this mailing list and don't go to Nanog events, and there are surly a large number of them.

I think one thing the CIDR report glosses over, with its ranking system is the sheer number of ASes which announce extra routes.   At least that is what strikes me when I start punching my local peer (not customer) ASes into the cidr-report website, virtually all of them have an aggregation problem and by percentage of junk announcements, the small ASes are often far worse than the big guys.

That being said, perhaps we need some sort of nanog outreach or BGP support community that larger (or clue full) providers can point their less clue full BGP customers towards.   The question then becomes, who would maintain such a group and how do we get the large number of currently non-participating ASes involved?

Well said.  At NANOG you get the clueful people cuz they at least knew to 
come.  That is a start.  But there are hundreds of ISPs out there who don't 
have a clue.  RIPE realized this without having to do a membership poll and 
rightly so, goes and does training where it is needed (and believe me - I 
am their biggest critic and all-around pain in the ass when it comes to 
their expenses as Leo and Rob can attest).

NANOG is not the place to do it.  ARIN, as part of their overhead should do 
an east coast, west coast and Chicago area tutorial at least once a 
year.  And guess what - most of the training material has already been 
written by the other RIRs.
