Help with Static Routing

josbro04

Hey guys,

For some reason, I am stuck on static Routing. I understand the concept but for some reason, I cannot apply it. HELP

DevilWAH

a bit more info please?

what exactly are you trying to apply?

under config mode

conf#ip router <destination ip> <destination mask> <next hop ip or interface>

all it is saying is traffic to this network send out this interface, trafice to this network send out this interface.. ect..

If I could send someone a pdf File, you can see what I mean and need help with

miller811

Post the title of the book and the section that you are studying from.

Its not a book. Im using cisco's Packet tracers to help me study. I have pdfs to go with the activities.

Might be a good idea to grab a book and learn the concepts and understand whats going on before trying to configure it...

I have read and studied this tons of times. I just think I am missing something and need help.

Just explain what the problem is man. No one can help you if we don't know the problem.

I have 4 networks off of the same Router

172.24.0.0/16
172.25.0.0/16
172.26.0.0/16
172.27.0.0/16

I need to make a static route from another router to this network.

I did ip route 172.1.0.0 255.255.0.0 ...... but it did not work. What am I messing up

check your PM box

Yep I think you need to learn subnetting, as there is a clear problem with that config.


If you still having issues let me know.

Is the 'ip route 172.1.0.0 255.255.0.0 ......' line you have above meant to point towards the four networks?

hexem

Ok.

For each remote network that you have there, you need to put a static route for each.


ip route 172.24.0.0 255.255.0.0 (next hop / or outgoing interface)
ip route 172.25.0.0 255.255.0.0
ip route 172.26.0.0 255.255.0.0
ip route 172.27.0.0 255.255.0.0

Now the router will be able to route traffic to those network's, but you will not get a reply unless the other router also has route's back from the subnet's you are coming from.

Exactly what hexem said. Better get this down because RIP v1 and auto summarization is coming. You will need to understand it.

Here is a screenshot of what I am trying to do. Ip addresses are there.

Router HQ should only have 2 static Routes. what are they?

Dilbert65

Assuming the IP addres on S0/0/0 on B1 is 172.30.0.1 and you want traffic from router HQ 172.12.0.0 range to go to B1 then:


ip route 172.27.0.0 255.255.0.0 172.30.0.1

ip route (source traffic ip/mask) (ip or exit interface to where you want it to go )
Personally I would alway use the IP adress of the downstream router.
To save yourself some hassle ping the downstream ip first before you put the route in.

When you stuck on a command mak sure to do something like this

ip route 172.27.0.0 255.255.0.0 ? <enter>

Well, the activity wants Interface. Not sure why you came up with 172.27.0.0 but I tried it. I type the following:
ip route 172.27.0.0 255.255.0.0 s0/0/0

It did not work

The syntax of the command is not the issue. I wounder if this activity is messed up

It wants me to use interface. BUt what you type is basically what I tried the first time and it did not work. I wonder if the activity is messed up or something

What didn't work exactly?

Bear in mind that routers B1 and B2 won't know about networks 192.168.64.0/24 and 192.168.65.0/24.

So if you are testing by pinging say PC10 from PC5 the traffic will know how to get to PC10 because of the ip route statements on HQ but the return traffic won't know how to get back to PC5 because of the lack of an ip route statement on B2.

Soooo,

HQ

ip route 192.168.0.0 255.255.252.0 S0/0/1
ip route 172.24.0.0 255.255.252.0 S0/0/0

B1

ip route 192.168.64.0 255.255.255.0 S0/0/0
ip route 172.24.65.0 255.255.255.0 S0/0/0

B2

ip route 192.168.64.0 255.255.255.0 S0/0/0
ip route 192.168.65.0 255.255.255.0 S0/0/0

CHeck your mask cause that mask on IP's cause only ip's

172.12.0.1 and 172.12.0.2 will get traffic routed.

try using a full class b mask to see if that works then start shinking your mask.

here is a handy online subnet calc that I find usefull

Why is the subnet mask 255.255.252.0?

I tried it and did not work

What do you mean it didn't work?

Also, why are you doing this excercise in the first place?
What topics are you studying?

It didnt work, I put in exactly what you told my and it didnt work.

Im just running through everything. Im going from top to bottom.

for a /16 and a /24, why would you put a /30 into the static route? Maybe its something Im missing?

Dilbert65

After taking a closer look at your pic none of the links seem t be up. I dont see alot of green between the links. Also did you put a default gateway on the pc's.

I have not use packet tracer for some time but I remember the links should be green

on HQ run "show int s/0/0/0" and see if it is up. then do the following on all the routers int's even b1. Start small and from pc5 try to ping the gateway on HQ.

Once again, what didn't work? What are you trying to achieve here? After you enter the ip route statements how are you testing connectivity?

You wouldn't put a /30 in. 255.255.252.0 is a /22.

I think you need to go back and study IP addressing, subnetting and route summarization.

Part of the reason why there isnt alot of green is because I just started the thing. It grades you for each thing you do right no matter what order you do it in. I kept having problems with these 2 routes and thats why I restarted the packet tracers, did a few interfaces and worked on the static route. Im stuck at 44% and everytime I try another static route, it does not work and the percentage does not go up

I apologize, I ment /22. I know ip addressing and subnetting. that was a simple mistake.

Everytime you do somethign correct in the activity, your percent correct goes up. When I enter what you told me, my percentage does not go up. I also check to see what I still need to complete to get 100% and it says the 2 static route for HQ. Thats how I know

hexem

Packet tracer is buggy and sometimes you just don't get the results you expect.

Try a clean packet tracer file recreating what's there and you'll prolly find it does work.

thenjduke

can you please send me the packet file?
