Quick list of long prefixes.

["Photon [NOL Staff]" <[e-mail]>]

For my own curiosity, I generated a list of /20 or greater prefixes our 
routers were hearing across the net.  I realize that there are many reasons
to advertise /2[0123] nets individually, but I think there is probably
rarely a good one for /24 and greater advertisements. (Yes, there are
quite a few which are greater than /24, even several /32's).

Anyways, I put the list I generated (which simply lists all the long prefix
advertisements, followed by their originating AS, one per line) up in a
personal ftp directory, as well as the short script I wrote to generate this
list from the output of Cisco's "show ip bgp" command.

The list and script can be obtained from:

	ftp.nol.net:/pub/users/photon

There are only three files in there at this time, all of which are 
related to this issue.

If everyone would take the time to grep the list for their own AS 
numbers, maybe some people will realize advertisements they didn't think 
they were advertising, or decide to finally aggregate a few things...

Disclaimer: I don't gaurantee that I didn't make up the numbers in the 
list randomly, and I'm quite sure it is slightly inaccurate, since I 
don't have a very good view from here (I'm not in any major NAP/MAE's).
I only claim that it has the slight possibility of amusing readers of the 
bgp mailing list.
