OSPF Demystified With RFC Version 3.1: RFC Translated Into Practice Kindle Edition



OSPF Demystified With RFC is the only book in the market and in the world that will allow you to understand OSPF with atypical scenarios that you will not find anywhere else. Scenarios with suboptimal routing and routing loop, scenarios with challenges and scenarios that explain what happen inside OSPF for path selection and why this happen ? each scenario et each behavior is referenced by its RFC and its section.

To understand the operation of OSPF you should be familiar with a core set of RFCs (Request for Comments) that defines OSPF. This ebook gives you a large view in order to understand the effect of the following RFCs : 3101, 1587, 1583, 2328, 5340 and 3509 on OSPF path selection either for external routes or internal routes, summary route cost , LSA Type preference etc…., and to see the difference between them in practice. The Labs are elaborated step by step with some challenges and explanations. It is important to know that depending to the RFC you implement, the path selection differs and enabling or disabling an RFC is possible since the compatible command is available in IOS Cisco Routers 15 and later, it gives you a choice to implement the necessary RFC according to your requirements. Most engineer ignores the importance of RFC with OSPF, and you can find through this ebook different scenarios that show the behavior of each RFC and see OSPF behavior when you change the RFC compatibility.
