Cidr Report in parts - part 1
by Tony Bates 28 Sep '96

28 Sep '96

Due to what I'm guessing is a problem with the merit mailer it seems to eat my mail message containing the full report so I going to break it up in part to see how that works. --Tony This is an auto-generated mail on Fri Sep 27 12:01:14 PDT 1996 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me. In the future I hope to put some (or most) of this report up on the web. ------------------------------------------------------------------------------ CIDR REPORT for 27Sep96 0) General Status Table History ------------- Date Prefixes 210996 43100 220996 42436 230996 42636 240996 42498 250996 41621 260996 42422 270996 42323 Possible Bogus Routes --------------------- *** Bogus 211.199.11.0 from AS6176 AS Summary ---------- Number of ASes in routing system: 1630 Number of ASes announcing only one prefix: 644 (330 cidr, 314 classful) Largest number of cidr routes: 493 announced by AS3561 Largest number of classful routes: 1268 announced by AS174

Looks like Solaris has the same bug as the ATM link you described. I see every other packet dropped by a Solaris box on my ethernet but not by a linux box on the same ethernet.

No, it's not a Sun issue, it drops every other packet only if I got over the ATM Backbone. I can trace to another router, a ATM Switch, A CSU panel, anything and I get the same dropped packet. I did further testing, and it is every other packet, not just the middle one.

I bet you that ns2.acsi.net is a Solaris 2 box. Solaris drops every other icmp echo if it comes too close to the last one. This I was told is an inadvertent bug although Sun could claim it to be a feature against an ICMP flood attack ;-) Try tracerouting to sun.com (a SunOS box) and playground.sun.com (Solaris 2). You'll see the difference. Also try traceroute with the -q parameter greater than the default of 3 packets each destination.

RE: Advice on dealing with Sprint
by cdc＠GroupZ.net 27 Sep '96

27 Sep '96

I called Sprint. They said to multihome, load balance across to distinct backbones (i.e Sprint & UUNET), and accept the full routing table, I'd have to use a 7000 series. I didn't believe them, so I logged a call with the TAC. They said they knew of no technical reason why the 4500 wouldn't do the trick, but maybe I should call my sales engineer. My sales engineer said the 4500 would to the trick (of course they'd prefer to sell me a 7000), but I might have to accept reduced routes or perform some other kludge to reduce the load on the router; and no telling what the performance would be like 2 months from now. Note: Our primary interest is bypassing problems we're experiencing between Sprint and UUNET via MAE-E, but we'd like to offer the best connectivity to our web servers. I called Sprint back, and they said they could work out a 'Special Customer Arrangement' to deal with the 4500. Based on the e-mail addresses I see on this group, it seems like we should be able to come to some consensus about the viability/sensibility/performance related issues related to this topology. > > I'm extremely suprised that this is their stance.
