    +

    +

    I’ve already done one post regarding EIGRP, but I said I was going to do a second post going over a few more advanced topics regarding EIGRP routing protocol. Check out my previous EIGRP post by clicking here. EIGRP uses Hello packets to check that their neighbors are still active,…

    OSPF stands for Open Shortest Path First it is an interior gateway routing protocol. OSPF is a link-state routing protocol. OSPF is my go to protocol that I like working with, OSPF is not a vendor specific protocol, a number of vendors also run OSPF on their networking devices, I’ve…

    Routes! Routes tell network packets how to traffic across the network to get to their required destination by picking the best path. There are three different types of routes such as default routes, static routes and dynamic routes. Each one has its own pros and cons.  Routes are stored in…

    Home Lab Setup for CCNA/CCNP/Networking There is always “the great debate” when you’re studying for your certification exams if you should build your lab with hardware or software. In my opinion, what I have done is gone with both. I think you should have 2-3 routers, 2 switches and sometime…

    Network switches mainly operate at layer 2 as well as layer 3 switches. Layer 3 switches combine layer 2 and layer 3 capabilities I’ll be going over mostly layer 2 switch functions for this post. Switch come in 2 different forms such as managed switches and unmanaged switches. unmanaged switches…
