Route Redistribution (Over?)Simplified…

Posted in Uncategorized by shaw38 on January 7, 2010

Here’s the best document on route redistribution I’ve read so far:

And it all can be summed up in this statement:

“Avoiding these types of problems is really quite simple: never announce the information originally received from routing process X back into routing process X.”

And it truly is that simple. Always mark/tag/color routes based on their source routing domain and when redistributing, select which routes to redistribute. After all, routes are merely destination information. It’s all about who needs to know and from whom they need to know it.
