It might happen on your CCNA exam, it might happen on your production network – but sooner or later, you’re going to have to perform password recovery on a Cisco router or switch. This involves manipulating the router’s configuration register, and that is enough to make some CCNA candidates and network administrators really nervous!
To pass the BSCI exam and move one step closer to CCNP certification success, you’ve got to know how and when to use debug commands to troubleshoot and verify network operations. While you should never practice debug commands on a production network, it’s important to get some hands-on experience with them and not rely on “router simulators” and… Read More »
As you study for your CCNA and CCNP exams, particularly if you’re getting hands-on practice in your home lab or rack rental service, you’re going to be sending a lot of pings.
Occasionally, during your CCNA and CCNP studies, you’ll run into a term that just doesn’t quite make sense to you. (Okay, more than occasionally!) One such term is “reverse telnet”. As a Cisco certification candidate, you know that telnet is simply a protocol that allows you to remotely connect to a networking device such as a router or… Read More »
OSPF short for Open Shortest Path First is a Routing Protocol used to select the best suitable route for packets within the network. OSPF basically an open standard protocol and not relate to any particular vendor. OSPF propagate the changes to all networks more quickly as compared to RIP and IGRP protocols then only send the changed part… Read More »
The main difference between RIPv1 and RIPv2 is classless routing. RIPv2 incorporates the addition of the network mask in the update to allow classless routing advertisements. This is extremely important for the flexibility needed to efficiently utilize network assignments for an ever-shrinking pool of IP addresses.
The sequence of events the bootstrap code follows to find the image follows.
