CCNA: Chapter 4-6 Route Redistribution
While you are not really going to redistribute routes as a part of CCNA, it is important to know what it is. Simply put, route redistribution is the process of distributing routes learned from one source to another.  This is useful when networks are expanding, or are merging, or in a phase of transition. For ...

CCNA: Chapter 4-5 Routing Loops
A routing loop is a situation where a packet keeps getting routed between two or more routers because of problems in the routing table. In case of distance vector protocols, the fact that these protocols route by rumor and have a slow convergence time can cause routing loops. To understand how routing loops can occur ...

CCNA: Chapter 4-4 Classes of Routing Protocols
Routing protocols are divided into the following three classes, depending on how they work: Distance Vector – Distance Vector protocols are characterized by two things: They use distance has a measure of the cost of a route. The number of hops in between a router and a destination network determines the distance. They periodically send ...

CCNA: Chapter 4-1 Understanding IP Routing
In the simplest terms, IP Routing is the process of moving packets from its source to its destination across internetworks. To be able to route packets, a router must know at a minimum the following: Destination address Neighbor routers from which it can learn about remote networks Possible routes to all remote networks The best ...

CCNA: Chapter 3-9 Cisco Discovery Protocol (CDP)
Cisco Discovery Protocol (CDP) is a proprietary protocol designed by Cisco to help in finding information about neighboring devices. Devices connected to each other exchange CDP packets to learn about each other. This can be useful in troubleshooting and documenting the network. CDP is enabled on all interfaces of all Cisco routers and switches. You ...

CCNA: Chapter  3-8 Password Recovery on a Cisco Router
While working with IOS based devices, it is not uncommon to forget passwords and lock yourself out of the devices. While password recovery procedures differ from device to device, most Cisco routers have a similar process for recovering the password. Recovering passwords for Cisco switches is a little different and not covered in CCNA, so ...
