Dynamic Routing Protocols

1: What is a routing protocol?

* A routing protocol is a "language" that routers speak to each other to share information about network destinations.

2: What basic procedures should a routing algorithm perform?

* At a minimum, a routing protocol should define procedures for:Passing reachability information about networks to other routersReceiving reachability information from other routersDetermining optimal routes based on the reachability information it has and for recording this information in a route tableReacting to, compensating for, and advertising topology changes in an internetwork

3: Why do routing protocols use metrics?

**A route metric, also called a route cost or a route distance, is used to determine the best path to a destination. Best is defined by the type of metric used.

4: What is convergence time?

* Convergence time is the time a group of routers take to complete the exchange of routing information.

5: What is load balancing? Name four different types of load balancing.

* Load balancing is the process of sending packets over multiple paths to the same destination.Four types of load balancing are:
a) Equal cost, per packet
b) Equal cost, per destination
c) Unequal cost, per packet
d) Unequal cost, per destination
