Many of the scalable design features
explored in the first two modules, such as load balancing and
route summarization, work very differently depending on the
routing protocol used. Routing protocols are the rules that govern
the exchange of routing information between routers. The open
architecture and global popularity of TCP/IP has encouraged the
development of more than a half-dozen prominent IP routing
protocols. Each protocol has a unique combination of strengths and
weaknesses. Because routing protocols are key to network
performance, there must be a clear understanding of the following
attributes of each protocol:
-
Convergence times
-
Overhead
-
Scalability features
This module explores various routing processes including default
routing, floating static routes, convergence, and route
calculation.
