Five reasons you need BGP in a Service Provider network

If you're a regular reader of my blog, I probably don't have to persuade you that BGP is one of the cornerstone technologies of modern Service Provider networks. However, if you ever find yourself in a situation where someone needs a nudge in the right direction, the article “5 essential reasons for BGP in your IP network” I wrote for SearchTelecom might come handy.

The list of all articles I wrote for SearchTelecom is available in the CT3 wiki.

  1. Excellent article.

    I noticed the title in the SearchTelecom version of the article omitted the words "Service Provider" - implying BGP is essential in all IP networks. This is clearly not the case. There are other solutions.

    These can work for mainstream enterprises too. That being said, thanks for an informative piece.

  2. Well, the site is focused exclusively on Service Providers (see its name), so one would expect the readers to be biased accordingly ;)

    As for the other links you've provided, I can't see what's the advantage they offer from technology standpoint. They might be more focused on the task at hand, offer the solution in a less convoluted way than what we do today with IOS, but there are only a few field-proven technologies that can build a large scalable network today, BGP being one of them.
