The Cidr Report

This is an auto-generated mail on Fri Feb 18 12:00:01 PST 2000 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

Hi, I have 2 questions regarding routing: 1. Should an end-node (not a router) have RIP enabled on its interfaces? What should its behaviour be, with and without RIP enabled. 2. Consider this set up: οΏ½---------- οΏ½---------- | R1 |--------------------------| R2 | οΏ½---------- οΏ½---------- ^ ^ 172.17.2.13 172.17.2.14 (ff.ff.ff.0) (ff.ff.ff.0) R1 has a static route configured . To reach 172.17.100.1 next hop is 172.17.4.1 R1 and R2 have RIP1 enabled on their interfaces. Does R1 advertise 172.17.100.0 also to R2, alongwith advertisement for host route 172.17.100.1 ? Thanks in advance for your help Anumita.

New tool announcement from Merit/IRRd: IRRj
by Jonathan Poland 22 Jan '00

22 Jan '00

Merit's IRRd team is pleased to announce the 1.0 Beta version of IRRj, a Java interface to the Internet Routing Registry. IRRj replaces the traditional e-mail submission process for database objects, and offers the following features: - Speed: IRRj opens a TCP socket connection to IRRd and provides fast, immediate feedback on the success or failure of your object submission. - Authentication: supports CRYPT-PW, PGP-FROM, and NONE authentication schemes transparently. - IRRd query support: offers full querying capabilities to retrieve objects for editing and resubmission. - Custom editing features: automatically appends delete fields to all objects, imports object templates. - Split window interface: IRRj includes a submission window and an IRRd feedback window. IRRj can be invoked from the Web or as a standalone application. System requirements are Sun's JDK (free from java.sun.com) Netscape 4.5+ or Java Plugin 1.2.2 (Internet Explorer or Netscape on Win32). IRRj runs on any Java capable machine, including Windows, Solaris, and most flavors of Unix. IRRj object submission will work with the RADB and any other IRR database that supports the IRRd synchronous object submission protocol. See http://www.irrd.net for more information about the freely available IRRd software. IRRj is freeware and can be downloaded and/or invoked from the web at: http://www.merit.edu/ipma/javairr/irr.html Please contact the IRRd team (irrd-support(a)merit.edu) with comments, feedback, suggestions, or questions.
