Hi guys,
I'm just messing with making a few Cisco networks but my mind has broken and I cant workout how to connect 2 routers lol.
Iv got green lights, but ping's don't work.
Below is a pic of what i have with IPs and fastethernet ports
subnet for everything is 255.255.255.0

What am I doing wrong, I hope its something simple so I feel like a douche :P

Thanks in advance!

The IP addresses are wrong on your router interfaces - wrong subnets. Change them to something else :)

The link between the 2 routers should be on its own unique subnet, (such as 192.0.30.1-2 going by your current scheme), and you will have to use a routing protocol or static routes so each router knows the network behind the other router.

Thanks for the replies gents, much appreciated.

I am however still slightly confused.

Iv put the link between the routers on a different IP and subnet.
Now Router 7's Fa 0/1 is 150.0.1.1 - 255.255.0.0
& Router 6's Fa 0/1 is 150.0.1.2 - 255.255.0.0

I'm now trying to set up this static routes. I'm not familiar with it but I gave it a go but it didn't like it :eek:
I selected Router 7 and entered:
Network: 150.0.1.1
Mask: 255.255.0.0
Next Hop: 150.0.1.2

Thats a total guess and i get an inconsistency error.

Sorry for being a total newbie but i would love to understand it.
Thanks again!
 
You've put the network address as 150.0.1.1 which is a host address, the network address should be 150.0.1.0

edit: but 150.0.1.0 is a directly connected network so a static route isn't really needed

So if I put the 2nd interface fa 0/1 or Router 7 to 150.0.1.0
Then what happens to Router 6's fa 0/1 ?
 
if you want to use 150.0.1.0 subnet for router to router, what you do is you set 1 router to 150.0.1.1 and the other to 150.0.1.2.

Routers already know what networks they are directly connected to, so you only need to add static routes for networks attached to foreign routers. So you would give router 7 the static route for the 192.0.20.0 network, and router 6 would need to be given the static route for 192.0.10.0.

As said the router interface IPs would remain the same but when you add a static route the destination network address should be the network address (binary equivalent of all 0s in the host portion of the IP)

ip route 150.0.1.0 255.255.0.0 150.0.1.2
not
ip route 150.0.1.1 255.255.0.0 150.0.1.2

Or as Dist said, more likely

ip route 192.0.20.0 255.255.255.0 150.0.1.2

Right I have done this, all accepted no errors but ping's don't go between the client pc's on the other network

Ill recap what I have to make sure it is correct.

Router 7:
Fastethernet 0/0 192.0.10.1 255.255.255.0
Fastethernet 0/1 150.0.1.1 255.255.0.0

ip route 192.0.10.0 255.255.255.0 150.0.1.2

Router 6:
Fastethernet 0/0 192.0.20.1 255.255.255.0
Fastethernet 0/1 150.0.1.2 255.255.0.0

ip route 192.0.20.0 255.255.255.0 150.0.1.1

Hows that?
Thanks a lot guys really do appreciate the help.
 
The static routes are slightly wrong, they're each mapping to an already connected network instead of the remote one

The format is:
ip route [destination network] [destination mask] [next hop to that network]

So router 7's static route to the destination network should be
ip route 192.0.20.0 255.255.255.0 150.0.1.2

Your a star mate, that makes perfect sence, I don't know why that path didn't occur to me.
Its all working now, ping is successful from one client over the network to the next client.

Thanks very much, Now to expand my network :D
