Cisco for dummies?
by Deepak Jain 08 Nov '96

08 Nov '96

(Assuming this hasn't already been done and I am the one that is uninformed) Has anyone though of how much money some publisher could make with a Cisco for Dummies<tm> book? Say it runs $49.95 and is 2000 pages. It has every obscure use of every command in say the IP IOS or Netflow Switching or everything Cisco makes [depending on size here] It strikes me that the UniversCD and the bound/hard copy manuals [including the ones from the classes] are not all that useful unless you remember the approximate syntax of the command or that it has been expanded in the next version of IOS. Lots of companies make books solely elaborating on the references provided by the manufacturer [ala Osborne on Borland and such]. It boggles my mind to figure how many they would probably sell [one for every customer router?] Then again, I guess Cisco would sell it at they standard rates. $1095 for the 3 volume set on CD.

The Cidr Report
by Tony Bates 08 Nov '96

08 Nov '96

This is an auto-generated mail on Fri Nov 8 12:00:00 PST 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 08Nov96 0) General Status Table History ------------- Date Prefixes 021196 42147 031196 41998 041196 43311 051196 42209 061196 42297 071196 42623 081196 42636 Possible Bogus Routes --------------------- *** Bogus 90.0.0.0 from AS4747 AS Summary ---------- Number of ASes in routing system: 1759 Number of ASes announcing only one prefix: 712 (364 cidr, 348 classful) Largest number of cidr routes: 459 announced by AS3561 Largest number of classful routes: 1570 announced by AS174 1) Gains by aggregating at the origin AS level --- 08Nov96 --- ASnum NetsNow NetsCIDR NetGain % Gain Description AS174 1570 1098 472 30.1% Performance Systems International AS3602 641 347 294 45.9% Intergrated Network Services Inc.

pmmon spam
by Daniel Simms 08 Nov '96

08 Nov '96

We got spammed today, but I'm not totally convinced of how it happened. Thus, this a sanity check for me. So, this is my theory. It seems like the spamee list was an alias on one of the Spammer's machines. The the From: field of the spam was that *same* alias. Then there was a wave autoresponses directly to that address. Then, the n(n-1) autobot free-for-alls ensued, since there were several dozen infobots on the spamee list. Is this plausable? Send comments my way. - --- begin original message ---

If Tim and Associates could give the ISP community, and the rest of the IP world a Nutshell Book on IOS/IP, the rest of the protocols could go to the devil for all I care. The fact is, _only_ the IP feature set would have enough of a market to make such a book worth doing. Maybe IPX, maybe. For TCP/IP, I would make sure a copy went to each of my customers while they wait for PcaBell to hook up the local loop. Should give them plenty of time to get up to speed.

BGP Configuration Problem
by Michael H. Lambert 08 Nov '96

08 Nov '96

We are having a BGP configuration problem which looks trivial but is not working the way we expect. I'm going to throw myself on the mercy of the court and ask for help. There are three routers A, B and C. These are in ASa, ASb and ASc, respectively. B imports 10.1.64/19 from A and 10.1/16 from C. What we were expecting was for B's route to the /19 to be via A, just because this is the more specific route. However, the only route (both in the BGP and routing tables on B) is for the entire /16 via C. I have a hunch that what is happening is that B is saying "gee, I can get to the entire /16 by going through C, so why bother with A". If I'm not mistaken, this can be fixed by introducing local_pref for both peers. Could someone please comment on this?

PCH routing service (was: CIX routing service)

What about transit to other metro exchanges? I thought that PCH was also handling that? Could you give the group details on your model? Will it scale? And then there was the issue of "new ISP education" that we talked about at AA Nanog. PCH does that, too, out of pure self interest (those unmeasurably low flapping rates). A great combination!
