    Hello, this is my first post here,
    anyways i am confused when Anthony tried to explain Dynamic tables, i know he said “it is automated” and uses few protocols. I just need a simplified version of it, since English is my 2nd language but i understand quite good don’t worry.

    Static routing is one that you setup and it isn’t expected to change (not often, at least). If there are any changes in the network, then you need to manually update the routing tables.

    Dynamic routing is the opposite. By using routing protocols, the network is able to automatically adjust to any changes in the network. For example, if one of your routers breaks, the network can automatically route traffic around the failure (if possible) until the problem is fixed.

    While a small network might use static routing, most larger networks will need to use dynamic routing in order to keep the network running smoothly.

    The link below has a more in-depth discussion.




    The whole point of routing, is to determine what “path” to take from point A to Point Z.

    In static routing, we tell a packet EXACTLY how to get somewhere, We define every step along the way, and for the way back.

    With dynamic routing, the routing protocols talk to each other, and ‘figure out’ what path take to get somewhere, and what path to take to get back. This is beneficial because when they are talking to each other, they can inform each other of routes that no longer exist.

    Think of static routing, like your mom’s hand-written directions to get to the store. Now imagine programming a car to get to the store and back with only those directions, what is going to happen if a part of that path is blocked? The car will stop, and won’t know of any other way. It simply isn’t aware of any other way to get there.

    Think of dynamic routing, like a modern gps, you program in the destination, and go. It ‘figures’ out the route along the way.



    Ah, Thank you all, it helped me understand better, much appreciated.
