This chapter covers the following topics, which you need to understand to pass the CCNP/CCDP/CCIP BSCI exam:
Integrated IS-IS operation
Integrated IS-IS design considerations
The topics in this chapter describe the routing protocol Integrated IS-IS by explaining its operation and design considerations. The detailed explanation of the routing protocol assumes knowledge of the general operation and purpose of routing protocols and, in particular, link-state routing protocols.
Because Integrated IS-IS is similar to the Open Shortest Path First (OSPF) protocol, you should read the chapters on OSPF and reinforce the fundamentals of link-state protocols.
