Appendix G. Which Routing Protocol?

Among all the thorny questions that network engineers are asked on a regular basis, probably among the hardest is this one:

My network currently runs Enhanced Interior Gateway Routing Protocol (EIGRP). Would I be better off if I switched to Open Shortest Path First (OSPF)?

You can replace the two protocols mentioned in this sentence with any pair of protocols among the advanced interior gateway protocols (OSPF, Intermediate System-to-Intermediate System [IS-IS] and EIGRP), and you have described a question that routing protocol engineers are asked probably thousands of times a year. Of course, convergence is always faster on the other side of the autonomous system boundary, so to speak, so it is always tempting ...
