2.1 Dynamic Routing

What is dynamic routing?

Send routes to other routers, updating the routing table in (almost) real time.

What are the advantages of dynamic routing?

No manual route calculations or management, new routes are populated automatically, and very scalable.

What are the disadvantages of dynamic routing?

Some router overhead is required and requires some initial configuration to work properly.

What are the steps of dynamic routing protocols?

Listen for subnet information from other routers, provides subnet information to other routers, determine the best path based on this information, and when network changes occur, update the available routes.

How do you know which routing protocol to use?

Based on the state of the link or how far away it is, and it also depends on the type of router you have.

What is Enhanced Interior Gateway Routing Protocol (EIGRP)?

A partly proprietary Cisco routing protocol commonly used on internal Cisco-routed networks.

What are the advantages of EIGRP?

Relatively easy to enable and use, cleanly manages topology changes, and minimize bandwidth.
