Static route configuration | Network Fundamentals Part 18

Anyone who’s interested in networking should be interested in routing. It’s one of the core functions that we need to work with.

‘Routing’ is how a router (or multi-layer switch) will forward packets through the network. The router will build a routing table, where it puts routes. A route is a pointer to a network. It says ‘for this network, send traffic this way…’

Each router has a routing table, and each router needs to make its own decisions around how packets should be forwarded. These decisions will depend on the contents of the routing table.

One of the ways we can ‘populate’ the routing table is to configure static routes. These are configured with the ‘ip route’ command. Another way is to use dynamic routing, which is covered in the next video.

Just like PC’s, routers can have a default gateway, also known as a ‘gateway of last resort’. This is a ‘catch-all’ route that is used to forward traffic that doesn’t match any other more specific rule.

Be sure to check out the labs (links below) if you want to try this out yourself.

Thank you once again sir for your awesome and clear content ! I like the fact that you challenge us to figure somethings out and work through problems. I can definitely be thankful for your help into my IT career and your content is always a blessing to me. Keep up the great work. Have a wonderful Thanksgiving and God Bless you and your family.

As usual you only post useful and easy to follow videos.. keep the good work man.
Can you do series about routing protocols?

Thanks

literally just saved 20% from my GPA thanks man

Really enjoying and appreciate your videos. I found this one a bit too fast-paced relative to the other fundamental courses but can't give up now.

Great video I was wondering if you'd be able to help me out I need a hand changing my routers NAT type it's currently set to strict I need it to be open. Or moderate

Like then watch & learn
These are the rules

at min 1:30 you tried to ping 192.168.3.3 - but there is no (device) connected to that network 192.168.3.0/24 ... so it will fail anyways ...no ?

bruh i need the rest of these videos my exam is on monday

Question: 4:45min why is <next-hop> 172.16.0.3 ? How did you come up with this ip ?

Good video, but you never got around to explaining the numbers in the [] in the routing table.

Hello there! I have a "high-level" question(s) to ask and if you could kindly provide your professional feedback. I have a firewall that has a ethernet cable connected on X0 to the core switch. In that firewall, the physical interface has an IP address of 10.8.10.1/24 and inside that physical interface, there are muplite virtual interface (Sonicwall way of calling it). In the core switch, there are static routes and a default route (gateway of last resort) that's written 0.0.0.0/0 10.8.10.1 because that's the network in building #0 "10.8.10.0 network". But then I noticed the firewall's virtual interfaces for other networks, it has a IP address and other L3 switches for those offices has their own default (i.e. 0.0.0.0/0 10.8.0.1 build #1, 0.0.0.0/0 10.8.1.1 build #2, and etc.). But there is one building that does not have a default route that lives in that switch, the default route or statis route is on the firewall that was created and it points to the gateway/interface of 10.8.10.1 and that's how it routes to the internet. This network was not build by me, it was done by my predecessor. My question is, we're having a new building coming up soon and the switch we will connect via fiber and will be configured as a L2, so instead of creating a SVI on the switch and core switch, I would need to create a static route on the firewall and point it to the gateway/interface of 10.8.10.1. Is that how it done so it can have internet access? This seems new to me or maybe I am not understanding it. Thanks for your time.

And next up we have dynamic or "random" routing & their protocols.
