Yet another of topic message;) I'm looking for IP transit in Newfoundland, since I'm not familiar with that territory, I was hoping that someone could message me offline for available options. Regards MKS

BGP Timers Configuration
by ahmed＠simula.no 25 Aug '08

25 Aug '08

Folks, We are pursuing some work along the lines of studying BGP scalability in terms of churn evolution. One of the key mechanisms used by BGP to dampen the churn is the MRAI timer (Minimum Route Advertisement Interval). >From different vendors' specifications we find that: 1- Cisco enables MRAI by default for both route announcements and route withdrawals. 2- Juniper has a similar parameter called out-delay which is disabled by default. Of course these are default configurations, and we don't know if ISPs use them without any change. We would appreciate any input on the following questions: A- Is it common that ISPs change MRAI default configurations? If yes, then what decides the MRAI settings for both e-BGP and i-BGP sessions? B- Does anybody use a configuration where only route announcements are rate limited, and not explicit route withdrawals? C- Are there configurations where rate limiting is applied only to a subset of session? Best regards, Ahmed Elmokashfi Simula Research Laboratory.

Re: Force10 Gear - Opinions

They came and did their > whole dog and pony show today, but I wanted to get real-world feedback > on their gear. I was at a customer site doing a NAC deployment study recently ( <6 months ago) and there was some Force10 edge gear in place. We had to drop the Force10 gear out of the picture because it didn't support any of the rich features that we needed to get NAC up and running. The customer was perfectly happy with the ability of the stuff to pass packets and act as a not-very-smart edge switch, and hadn't evaluated the feature set for anything beyond that. My conclusion was that if you want to use it at the edge to pass a lot of packets at 'enterprise' line rates and don't care about anything else (we were looking at good 802.1X support with ACLs and all of the other miscellaneous bits that make NAC work, YMMV) then it seems to be fine per this customer's experience. If you want something with a stronger feature set for future expansion, there seem to be other companies that have more experience. In David Newman's test of 10G edge switches (http://www.networkworld.com/reviews/2008/032408-switch-test.html) Force10 elected not to participate, which is often telling. jms Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms(a)Opus1.COM http://www.opus1.com/jms
