There was a lot of blogging related to OSPF topics recently. In this post, I would like to clarify some common misunderstandings that many people have about OSPF route filtering. I have seen so many folks (some of them really experienced persons!) incorrectly understanding the underlying behavior so it’s about time to make this clear. Oh, as a matter of fact, making “everything clear” is one of the primary goals of the new 5-Day Kickstart Bootcamp (ad here!) which targets in-depth technology explanations ;) ...
