The Cidr Report

This is an auto-generated mail on Fri Oct 18 12:00:00 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 18Oct96 0) General Status Table History ------------- Date Prefixes 121096 41682 131096 41496 141096 41671 151096 42238 161096 42202 171096 42175 181096 42347 Possible Bogus Routes --------------------- *** Bogus 211.199.11.0 from AS6176 AS Summary ---------- Number of ASes in routing system: 1705 Number of ASes announcing only one prefix: 685 (353 cidr, 332 classful) Largest number of cidr routes: 530 announced by AS3561 Largest number of classful routes: 1246 announced by AS174 1) Gains by aggregating at the origin AS level --- 18Oct96 --- ASnum NetsNow NetsCIDR NetGain % Gain Description AS174 1246 918 328 26.3% Performance Systems International AS3602 623 329 294 47.2% Intergrated Network Services Inc.

Provider P allocates a block of address space A to customer, I an ISP. I allocates a /24, call it B, out of that block to one of their customers, C. C later leaves ISP I and gets a wire directly from provider P. I wishes to give C time to renumber. I would expect the world to see the following announcements. A - I announcing a shorter prefix, A B - P announcing a more specific for the /24 allocated to C Is this not what we all expect? Why I ask is we have provider P telling I that they should stop announcing A and instead announce a bunch of prefixes around the /24. randy

Hank, Have your tried to replicate your customer's problem? We have tested setting the prefix mask in the IP stack in NT 4.0 and it can be set to prefixes longer than 24. cheers, peter >---------- >From: Hank Nussbacher[SMTP:hank@ibm.net.il] >Sent: Wednesday, October 16, 1996 7:47 AM >To: nanog(a)merit.edu >Subject: Windows/NT to break the Internet? > >How long can the Internet last if every customer needs to get a /24? >That is what appears to be with Windows/NT 4.0.

I'm seldom able to get specific, substantive criticisms from people who make comments like these, other than to say that the configuration language is not obvious and not well-documented (I agree, for now). Like any piece of software, gated does of course have some bugs in it, but I haven't seen evidence that it has more or more egregious bugs than other routing protocol implementations. And it gets a lot of things right that some people don't -- for example, it sends withdraws only for routes it has announced. I could go on, but I won't. The bugs are, of course, being worked on as they are found, just as with any other software. IMO gated's stability is pretty decent at this point. Likewise, it's missing some features, which are also being worked on. The proof of the pudding is of course in real-world use. As I assume most people on this list know, more than one large, respected backbone operator uses (or has used until recently) gated as their routing software, for quite some time. I've seen no evidence to suggest that gated is problematic for them; quite the contrary.

Any chance we could have some 10BaseT along with the thin coax? Then I can leave my coax dongle at home. Thanks in advance for better connectivity. --Kent
