In preparation of our CCNA exam, we want to make sure we cover the various concepts that we could see on our Cisco CCNA exam. So to assist you, below we will discuss Cisco CCNA Routing Cliff Notes.
Below we are going to review at a high level various routing protocols that will run on your Cisco routers. Routing is at the core of what you are learning for your Cisco CCNA exam and if you don’t understand how a Cisco router routes, well you have no chance at passing the Cisco CCNA exam. As I am sure you are aware, Cisco is the global leader in networking because of their Cisco router and Cisco switches.
The first thing you must be aware of is the difference between a routing protocol and a routable protocol. An example of a routing protocol is RIP or OSPF. They exchange information among Cisco routers to generate routing tables. An example of a routable protocol is TCP/IP or IPX/SPX. Netbeui is an example of a non-routable protocol. Which in essence means it does not understand different subnets. It only thinks the network is one big subnet that can’t be divided into multiple or smaller subnets. This is why in such a network you have lots of collisions as you have no way to segment the network to break up the network traffic into difference broadcast domains.
Static Routing: Directs traffic to a specified network or group of networks. The syntax for this command is:
Router (config)# ip route destination_netwak mask (next_hop_ip I out going interface)
