Can somebody for the love of god explain Static Routing?

Some context: I am in ‘college’ right now. I was on the top of my class and so the school decided to transfer me to a more dificult class. On monday i was in my normal class and some teacher wanted to speak with me and then on tueseday i was in the more difficult class. Without preparing or books or whatever. This class has Cisco lessons and when you graduate you get your CCNA, i think at least you get it. But yeah i missed the first couple of months of Cisco lessons.
Now the teacher send us all a Packet Tracer file and we had to configure it so every computer can ping each other. I can do this with RIP but i have no idea how to do it with just statiic routing.

So here is my network:

The Fast Ethernet interfaces on the router are just 172.[routernumber].0.1. The Serial interfaces are 192.168.[somenumber].[routernumber]. So for router 22 the fa ip is 172.22.0.1 and the serial is 192.168.7.22.

I am trying to get the PC that is hooked up to router 22 to ping the PC that is hooked up to router 21. But it doesn’t work and i don’t know why. I have never had a lesson is static routing btw.

So what i do is i go in to the CLI of router22 and i type ‘ip route 172.21.0.0 255.255.0.0 192.168.7.21’. But it doesn’t work and i don’t know why.

Sorry if it doesn’t make sense but i’m desperate because i’ll have to have this assingment done tomorrow and have a test in this next week.

Thanks in advance.

Maybe those resources can help:

http://www.cisco.com/c/en/us/td/docs/security/asa/asa82/configuration/guide/config/route_static.html

http://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/27082-ip-static-routes.html

A static route in general is a pre defined rout to the next hop, where you determine explicit what the next hop is.

So in your example network the pc 172.18.10.1 can go to the pc 172.16.10.1 over three ways, but a static route in Router 18 and 16 will force the traffic to go between those and minimize the hopes compared to a route over router 17 or even over router 19 through out 11.

I hope I got that right, I had to leave school before finishing the CCNA though.

I made a big cup of coffee and a sandwich. Read your post and the resources you linked and after that it all made sense. Thank you very, very much. Finally it makes sense.

Opened the network and added the routes and now the computers can ping each other!

Altough you did not get your CCNA that had that right! :)
