Route Maps and Distribution Lists


I spent most of my afternoon covering the topics for Route Maps and Distribution Lists. I've actually been waiting to get to this topic for quite awhile because I see these commands in my work environment all the time. Both of these tools are similar to access-lists but their purpose is to tune or route specific IP packets. Distribution lists filter routing updates which is something you can't do with a regular access-list. Route maps gives the engineer a lot of flexibility on what specific ip packets should be tuned and what should be tuned such as the router metric. Tomorrow I will learn more about tuning administrative distance (AD) to control the flow of routing packets.
