Know that the default administrative distance (AD) values are connected (0), static (1), IGRP (100), OSPF (110), IS-IS (115), and RIP (120). Know the different AD values for internal and external EIGRP and BGP as well. -
Know and understand the following formula for calculating IGRP metrics: Metric=(K1xbandwidth)+[(K2xbandwidth)[db](256-load)]+(K3 x delay) -
Understand the differences between classless and classful protocols, as well as distance vector and link-state protocols (OSPF versus RIPv1). -
Have a grasp of the convergence process, as well as the components of a routing table. -
Be able to compare and contrast the general characteristics of RIPv1, RIPv2, IGRP, EIGRP, OSPF, IS-IS, EIGRP, and BGP. -
Know the fundamental differences between distance vector routing protocols and link-state routing protocols. |
