For instance, 212.x.y.z is "known" to be on one continent, and so on - but how do you leverage that into a 212/8 routing entry?
Well, suppose we know 212/8 is used in Europe. A network that is present in say, North America and Europe then has the routers in Europe that talk to the routers in America filter out all 212/8 more specifics and only announce the aggregate instead. In the simple version this only works if there is full interconnection for all 212/8 destination in Europe.
And if everyone gives transit to anyone. Ideal world. Elmi. -- "Begehe nur nicht den Fehler, Meinung durch Sachverstand zu substituieren." (PLemken, <bu6o7e$e6v0p$2@ID-31.news.uni-berlin.de>) --------------------------------------------------------------[ ELMI-RIPE ]---
