Having trouble setting up, probably the most basic setup ever. (Beginner)

We have a lease line and two 2600 routers each fitted with a WIC-1T. I’m trying to setup our routers for network traffic can go between each network, the setup is as below

Network A 10.0.0.0 255.255.0.0 => Router: rugeley

Network B 11.0.0.0 255.255.0.0 => Router: scotland

f0/0 10.0.0.150 s0/0 192.168.1.2 <-----> s0/0 192.168.1.3 f0/0 11.0.0.150

The config is as below (I can ping each of the f0/0 interfaces from either router but can’t see the network behind them)

hostname rugeley

!

enable secret xxxxx.

!

ip subnet-zero

!

!

interface FastEthernet0/0

ip address 10.0.0.150 255.0.0.0

End

Thanks in advance for you help

(Btw) this is my first attempt ever at setting up a Cisco router so I’m probably well off

You are using RIP which is a classful protocol. The easiest solution is to convert it to RIP v2 by

ROuter Rugely: router rip

ROuter Rugely: rip version 2

Do this for both routers. You should then be able to see out.

Also, from Rugely, you need to remove the Network 11.x.x.x. statement, because you are not advertising that network as originating in Rugely.

And similar from Scotland, remove the network 10.x.x.x statement from your RIP config.

You do not need the route statements either because this is the job of the routing protocol. So you can remove all the statements of the form IP route x.x.x.x

Also, disable ip http server. This is a known vulnerability in Cisco IOS.

You may also want to secure your telnet/console login with secure passwords. And when posting, remove the passwords from the text file before you post, even if they are encrypted.

You can also remove the access-list xxxxxx stateements. They aren't performing anything here.

Hope that helps.

Thanks for your reply I have now setup the routers as you have explained above the problem now is that the rugeley router is receiving the scotlands network

C 10.0.0.0/8 is directly connected, FastEthernet0/0

R 11.0.0.0/8 [120/1] via 192.168.1.3, 00:00:04, Serial0/0

192.168.1.0/32 is subnetted, 1 subnets

C 192.168.1.3 is directly connected, Serial0/0

C 192.168.0.0/16 is directly connected, Serial0/0

But the rugeley is not broadcasting its network to the scotland router I am completely lost as the setup are the same any ideas ?

Many Thanks

Andy

Can you post the two configs.

The only difference I can see is that you are using /16 mask for Scotland's FastEthernet IP address and /8 for Rugeley's FastEthernet IP address.

Please change Rugeley's to /16 (255.255.0.0) and try.

HTH

[a_jam_sandwich]

I have changed the setup as you explained above still nothing

Rugeley see scotlands network

Scotland doesn't see rugeleys network

[e.systems]

Jolmos right, you are advertising a /8 network, but your internal network is currently set to /16.

If changing subnet mask doesn't work, also try the following command on both routers

"no auto-summary"

If that doesn't work, can you post show ip route from both routers.

[a_jam_sandwich]

After making the change to the subnet the ip routes look like

<=== Rugeley ===>

rugeley#sh ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

have you assigned any interfaces as passive?

And the route table shows the opp's network at both routers now. I can ping either router no problem.

===================================================

Just configured the gateways and ip on both networks and success

Thank you all very much for your help
