Recap: Software to track IP Address
by Devon True 10 Feb '01

10 Feb '01

All, Thanks to everyone who replied. Several people asked that I post some of the suggestions that I received to NANOG, so here goes. :) Lucent QIP <http://qip.lucent.com> Granite Systems <http://www.granite.com> Nets <http://www.open.com.au/nets> Checkpoint MetaIP <http://www.checkpoint.com/products/metaip/> Tree <ftp://ftp.tic.com/pub/tree/tree-0.0.1.tar.gz> LanDB <http://avenir.dhs.org/landb/> Several people also replied that they are building their own database using either plain-text records or SQL databases (mySQL, PostgreSQL, mSQL, etc). I have personally looked at Tree and got a demo copy of Lucent QIP (No Windows 2000 server setup yet to test :) ). While testing tree, I found documentation and some of the more advanced "features" (e.g. email alerts, permission levels) were lacking. On the flip side, QIP and MetaIP have the ability to manage your DNS and DHCP services. While that is nice, I really don't need the functionality and it does drive the price higher. :( I would suggest trying out the above software. However, if they do not fit your needs, it looks like you have to build your own. ----- Devon True CCNA Tel: 502.315.6015 Xodiax Network Operations Fax: 502.315.6035 <louisville.noc(a)xodiax.com> URL: <www.xodiax.com>

Need help with Cisco VLAN bridging....
by Craig Holland 10 Feb '01

10 Feb '01

Has anyone had experience bridging multiple VLANs accross a clear-channel DS3? I have 2 3640's populated with 1 FE and 1 HSSI. They are connected by a DS3. I've tried a couple of different configs, including turning one router into a frame swich and building a PVC for each VLAN, but the bridging didn't seem to work. I've tried running SDE directly between the HSSI ports...and that didn't seem to work. I'm up a against a deadline here, and would greatly appreciate any help you can offer. I've also tried a couple of IRB configs. Thanks in advance, craig Craig Holland Network Engineer Yahoo! Inc. (408)731-3572 Y!Messenger: cholland

Billing systems
by Robbie Harrell 10 Feb '01

10 Feb '01

I am looking for information regarding ISP billing systems and feel this list is a great place to start my research. I want to evaluate next generation billing systems that have the following capabilities at a minimum IP support Usage based billing Robust Security Architecture Real time reporting Creation and management of user accounts Rapid provisioning of service offerings Activity tracking Rating Advanced billing capabilities International capabilities (Spanish a must) I would like to know what vendors play in this space and pro's and con's of any vendors you out there in the industry may have evaluated. Sample RFP's would be extremely helpful but I know that is a stretch. At a minimum, vendor names would be great. Thanks in advance!!!

Source Route Bridging / Source Route Transparent / ST - TB
by Wojtek Zlobicki 10 Feb '01

10 Feb '01

Anyone have some good resources on Source Route Bridging and all its variations. I would prefer vendor independent info but would be happy with almost anything. I am looking for behavioral information mostly. The way that the protocol behaves in different situations.

RE: BGP Question - how do work around pigheaded ISPs

Funny you should mention that... If I was a customer of ISPph, they would accept any route I send them in that block, so I guess $$$ might be another solution. But why would I be a customer of ISPph, if they don't provide access to the *entire* Internet? IMO, that makes them not be a real ISP, just a Partial-Network-SP. So far, we get traceroutes from users of ISPph who can't get to a site on the /19 block, and the answer back to them is "yours is the only ISP that cannot get to our network" and we suggest they get one of the free dial accounts just to prove to them that our site is up. Of course, the chances of enough users of ISPph complaining that it would make a difference is very slim.

Anything special with 172.31.0.0/24?
by Pim van Riezen 09 Feb '01

09 Feb '01

This sort of stuff really gets me puzzled. Why would anyone use IANA reserved space for probes, if the path back to respond to these probes will end up in the drain anyway? And why do I see so many from 172.31.0.0/24? Is this a Wintendo doing 7 bit over ethernet thinking it is multicasting?:) I'm wondering if anyone else is seeing more strange traffic from this particular range and/or has a theory.

Dotted lines on carriers maps
by Sean Donelan 09 Feb '01

09 Feb '01

Time to check the DLR's again. You know that dotted line on the map for your redudandent backup. Guess what the dotted line means? >From IDG.NET The China-U.S. Cable Network began operation in January 2000 with landings in California, South Korea, Japan, Taiwan and Guam. A second leg, which will create a loop and provide backup in case of a failure, is still under construction

outages as confidential information
by Sean Donelan 09 Feb '01

09 Feb '01

Last summer, some folks may remember I commented on the practice of CAISO not saying which plant tripped off-line leading to various stages of emergency during the summer. Several folks replied it was competitve information, and it would be illegal to release the information. The State of California has now ordered the California ISO to post daily lists, including the names, of power plants off-line for scheduled or unscheduled outages. Further the Governer has ordered utlities to provide advance notice to CAISO of future scheduled power plant shutdowns.

True, as you know, a "carrier-grade environment" can be pretty bad. I might as well ask, What is the MTBF after being exposed to the UPS shipping environment. Historically, the reason why I've tried to keep rotating storage media out of my critical POP equipment it requires too much maintenance. I'm old enough to remember routers with evil boot floppies. For non-critical stuff, like billing and accounting servers, rotating media is fine (speaking as a network geek, not an accounting geek). But maybe these microdrives are tough enough. I'm open to changing my mind.

The Cidr Report
by Tony Bates 09 Feb '01

09 Feb '01

This is an auto-generated mail on Fri Feb 9 12:00:00 PST 2001 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.
