GateD + OSPF Q
by Brandon Applegate 24 Feb '99

24 Feb '99

Would a question about GateD with OSPF be off topic for the list ?? If so, where should a post like this go ?? PS: We're not a GateD consortium member or anything, just and end user of the freely availible version.

Outages outside North America
by Sean Donelan 24 Feb '99

24 Feb '99

Since this is the North American list, I haven't been posting things about events outside of North America. Are there operation lists tracking trans-oceanic cables outages and similar things? I haven't looked, but does Canada or the UK have the equivalent of the FCC outage reports and public analysis? I'm guessing the cable didn't land in the USA because I didn't see anything hit the FCC about it. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

Re: honoring AS-path prepend from a peer or customer?
by Danny McPherson 22 Feb '99

22 Feb '99

Perhaps you should reread the original message regarding issues associated with honoring undocumented/misrepresented AS Paths.. As for what you mention below, perhaps you should have a look at the document referenced in the latter portion of my original message. I can say from several years of Operational experience, what you suggest below, in the context it's in, isn't a very good idea. There are much more intelligent mechanisms to obtain desired ingress and egress traffic distribution.. Now, perhaps applying policies or the like based on AS_PATH would be reasonable to some extent, but suppressing or manipulating specific path entries is only asking for trouble. Bedsides that, I'm not aware of any router vendor shipping code that would do anything along these lines, with the exception of the "private-AS" stuff that some support.. -danny Terence wrote: >It's very useful if you want to keep a link rather free of traffic in case >of a backup service from another NSP, and then when your big pipe goes >down, you have this other service with routes intact ready to roll without >intervention.

Mae-West (MFS location) has currently a power problem (since 9am PST) - in case you have some peers down, this is likely the problem. MFS Master ticket: 383730 - Martin Winter Exodus Communications (yeah.. our router is one of the affected ones :-( )

The Cidr Report
by Tony Bates 19 Feb '99

19 Feb '99

This is an auto-generated mail on Fri Feb 19 12:00:00 PST 1999 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.
