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

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 you can't explain it simply, you don't understand it well enough. Albert Einstein

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

OptionsDevilWAH Member Posts: 2,997 ■■■■■■■■□□Yep I think you need to learn subnetting, as there is a clear problem with that config.

Is the 'ip route 172.1.0.0 255.255.0.0 ......' line you have above meant to point towards the four networks?"There are 3 types of people in this world, those who can count and those who can't" -
Optionshexem Member Posts: 177Ok.
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.ICND1 - Passed 25/01/10

Exactly what hexem said. Better get this down because RIP v1 and auto summarization is coming. You will need to understand it.CCNA, MCP, MCSA, MCSE, MCDST, MCITP Enterprise Administrator, Working towards Networking BS. CCNP is Next. -
Optionsjosbro04 Member Posts: 15 ■□□□□□□□□□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? -
OptionsDilbert65 Member Posts: 73 ■■□□□□□□□□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

OptionsDilbert65 Member Posts: 73 ■■□□□□□□□□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?

What do you mean it didn't work?
Also, why are you doing this excercise in the first place?
What topics are you studying?"There are 3 types of people in this world, those who can count and those who can't" -

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? -
OptionsDilbert65 Member Posts: 73 ■■□□□□□□□□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."There are 3 types of people in this world, those who can count and those who can't" -

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 -
Optionshexem Member Posts: 177Packet 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.ICND1 - Passed 25/01/10
