Chapter 9: Link-State and Bridging Protocols


CCDA Exam Topics Covered in this Chapter:

  • Given a network design or a set of requirements evaluate a solution that meets routing protocol needs.

Sharing is one of the things children learn to do (or at least are usually encouraged to do). In today’s competitive business environment, sharing typically isn’t beneficial or desirable. But in routing, it has become essential. Most networks today are a mosaic of products from different vendors. It became obvious that protocols that created the opportunity for passing information using these different products were necessary.

OSPF and IS-IS are open standard routing protocols that allow Cisco routers to share routing information with other Cisco routers and with non-Cisco routers.

This chapter will introduce and discuss design implications for link-state routing using OSPF, Novell Link-State Protocol (NLSP), and IS-IS. This chapter will also explain the concept of bridging protocols.

Cisco has traditionally supported an extremely rich set of both routing and bridging functionality using a variety of Cisco proprietary and other protocols. Chapter 8, “Routing Protocols,” discussed the differences between distance-vector and link-state routing protocols, and then described several specific examples of each. This chapter will go into detail about OSPF, NLSP, and IS-IS. Then we will look at five types of bridging protocols and the situations where each would apply.

Topics covered in this chapter include:

  • The purpose and operation of routing protocols, including OSPF, NLSP, and IS-IS

  • The operation and implementation of source-route bridging, transparent bridging, and mixed media bridging
