Re: [WISPA] BGP Load Balancing Help
The simplest way is to prepend the DS3 circuit. Scott Vander Dussen wrote: On a single ImageStream router we have two circuits: DS3 @ 45mb/s Fiber @ 100mb/s The DS3 is routed more efficiently (less hops) and the fiber less efficient (more hops). Since the BGP is routing traffic based upon number of hops to final destination only, the DS3 gets 95+% of all our internal traffic. What can I do to shift some (or even possibly all) of the traffic to the Fiber to balance things out? Thanks in advance. `S WISPA Wants You!

Matt- Forgive my ignorance, I think this is where you're adding simulated hops or something similar, correct?

Re: [WISPA] BGP Load Balancing Help
Prepending is no longer the desirable solution and should only be used if your upstreams don't support a better way. The preferred way is to adjust local preference based on a route policy. You can simply prefer your fiber circuit if you want or adjust it on an AS basis. You will likely only want to consider the major carriers when doing this. For example, just the top ten carriers. You of course can only adjust local preference on your side affecting outbound traffic. To adjust local preference on the carrier side to affect inbound traffic you will need to have a carrier that supports communities. See http://onestepconsulting.net/communities/ for a good listing of carriers that support BGP communities. -Matt On Jan 17, 2010, at 8:41 PM, Matt Jenkins wrote: The simplest way is to prepend the DS3 circuit.

Re: [WISPA] BGP Load Balancing Help
Are the two providers same or different ? Depending on who the two providers are, you have have to use different techniques or a combination of them. (Local preference, AS Prepend etc.). There is hardly a cut and dry answer to this question anymore. Additionally, you also have to pay attention to what is the size of the network you are advertising via each of the two transit providers... Smaller advertised blocks take precedence over the larger blocks... If you want to go thru the learning experience, which is great, do some research on bpg configurations, CISCO has great articles on how it works along with a few other good articles on the net. Otherwise, there is no shame in contracting a savy Network Engineer to help you with this... There are a few who lurk on this list, just post a request, and you will get responses...

Re: [WISPA] BGP Load Balancing Help
AS Prepends don't work so well now-a-days. We have 3 full BGP feeds and keeping them balanced (incoming traffic) is quite a chore. It can be done, but it takes using communities and other BGP tricks. It would be worth finding a BGP Guru that can do some BGP magic and paying them a couple hundred $$'s to make it happen...

Re: [WISPA] BGP Load Balancing Help
Ok, thanks Travis, Faisal, and Matt for your input. We're looking to get this resolved quickly - so this is a formal petition for any BGP Gurus that have experience with the ImageStream OS - please send me an email off list. Or, any recommendations who I should contact? Thanks again. `S -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Travis Johnson Sent: Sunday, January 17, 2010 7:54 PM To: WISPA General List Subject: Re: [WISPA] BGP Load Balancing Help AS Prepends don't work so well now-a-days.

Re: [WISPA] BGP Load Balancing Help
Call ImageStream - they have 24/7 support. When I needed them to do a PPPOE client the first tech was wy off on the configuration. A day later I called back and got a hold of one of the techs that do it for their own home router (some DSL service) and got it running. Secondly Butch Evans does ImageStream. I've not had asked him to do any ImageStream work.
