The Mechanics of Routing
Routing is a complex set of mathematical processes that is embodied in highly specialized routing protocols. Routing protocols have numerous functions, including the following:
Discovery of neighboring routers (those that are directly connected).
Discovery of destination networks that are accessible via neighboring routers. After discovering destination network addresses, the router has a couple other chores:
- Comparing different paths (routes) to the same destination network. This is known as route calculation.
- Building a table of known destination networks and the corresponding router interface for each destination. This table is called the routing table.
This is a highly simplified explanation of the function of routing ...
