Border Gateway Protocol, Route Manipulation, and IP Multicast
This chapter covers the following subjects
- Route Manipulation
- IP Multicast Review
This chapter covers the Border Gateway Protocol (BGP), which is used to exchange routes between autonomous systems. It is most frequently used between enterprises and service providers. The "Route Manipulation" section covers route summarization and redistribution of route information between routing protocols. The CCDA should know where redistribution occurs when required by the network design. This chapter also reviews policy-based routing (PBR) as a method to change the destination IP address based on policies. Finally, this chapter covers IP multicast protocols.
