The Complete IS-IS Routing Protocol- P1:IS-IS has always been my favourite Interior Gateway Protocol. Its elegant simplicity, its well-structured data formats, its flexibility and easy extensibility are all appealing – IS-IS epitomizes link-state routing. Whether for this reason or others, IS-IS is the IGP of choice in some of the world’s largest networks. Thus, if one is at all interested in routing, it is well worth the time and effort to learn IS-IS. | The Complete ISIS Routing Protocol Hannes Gredler Walter Goralski J Springer The Complete IS-IS Routing Protocol Hannes Gredler and Walter Goralski The Complete IS-IS Routing Protocol 1 .
