This is likely true in some cases. But also note that some sites are registering more specific routes in the PRDB, but with the "no configure" flag turned on because an aggregate also exists. Such "no configure" flagged routes don't end up in the backbone configuration files and routing tables. You can't tell which routes have the "no configure" flag set from the NWG report. You would need to look at other reports or use the PRDB whois/show clients to make that assessment. --Steve Widmayer / Merit ***********************************************************************

Havard et al.--

As an adjunct to your comment, I would like to point out that several ASs/service providers continue to *add* nets which could be CIDRized (refer to any "Additions to the NSFNET policy-based routing database" messages sent by Steve Widmayer, Enke Chen, or myself to nwg@merit.edu; these are archived in the public FTP area on merit.edu under nwg-archive).

Hi,

as a casual reader of the reports Tony and Jessica automatically send out by the end of each week I feel that it is now pertinent to present a couple of points and invite some comments.

While some people are contributing their share by continuing to withdraw routes by actively using CIDR, I cannot avoid observing the fact that some of the larger and more well-respected Internet service providers week after week remain on the list of the "Top 10" ASes which could contribute substantially to the reduction of the IP routing table size by more actively using CIDR.

It is perhaps time to ask again why these service providers appear not to contribute their share to the common good?

What activities (besides these weekly automated postings here) are ongoing to push and guide these service providers in the right direction?

It seems clear that posting the "top 10" list although a useful thing in itself, is not enough to provide the necessary push. IMHO service providers on the list should feel a little more guilty than they apparently do right now.

Comments?

Regards,

- Havard
