The first post looked at problems with AS Path prepend, while the second looked at de-aggregating and using communities to modify the local preference within the upstream provider’s network.
There is one specific solution I want to discuss a bit more before I end this little series: de-aggregation. Advertising longer prefixes is the “big hammer” of routing; you should always be careful when advertising more specifics. The Default Free Zone (DFZ) is much like the “commons” of an old village. No-one actually “owns” the routing table in the global Internet, but everyone benefits from it. De-aggregating don’t really cost you anything, but it does cost everyone else something. It’s easy enough to inject another route into the routing table, but remember the longer prefix you inject shows up everywhere in the world. You’re fixing your problem by taking up some small amount of memory in every router that’s connected to the DFZ in the world. If everyone de-aggregates, everyone has to buy larger routers and more Continue reading
