Upon completing this lesson, you will be able to:
Describe the features and operation of static routing
Describe the features and operation of dynamic routing protocols, including RIP, IGRP, EIGRP, and OSPF
Build a functional router configuration to support the specified network operational requirements, given a network design
Use show commands to identify anomalies in routing operation, given an operational router
Use debug commands to identify events and anomalies in routing operation, given an operational router...
The following will be discussed in this chapter: Routing overview, static and dynamic route comparison, static route configuration, default route forwarding configuration, static route configuration verification, dynamic routing protocol overview, features of dynamic routing protocols, the IP classless command.
Every IP address must be accompanied by a subnet mask. By now you should be able to look
at an IP address and tell what class it is. Unfortunately your computer doesn’t think that way.
For your computer to determine the network and subnet portion of an IP address it must
“AND” the IP address with the subnet mask.When you take a single network such as 188.8.131.52 and divide it into five smaller networks
(184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, 126.96.36.199) the outside
world still sees the network as 192.100.10.
This chapter is devoted to the complex topic of IP-based emergency calls. What makes IPbased emergency calls a complex issue? First of all, an emergency call needs to be routed to the closest Public Safety Answering Point (PSAP). This requires the call to be routed to the PSAP based on the caller’s location, which in turns requires the caller’s location to be determined roughly.
