We just started working with Cisco routers and switches in our learning lab. (school)
We want to get a 2811 Router to do something simple. Just route two private networks 192.168.1.1/24 and 192.168.2.1/24
Our script runs in Packettracer 7.1 but not on the actual router.
Here is the script we are using with level 1 switches connected and static ip addresses.
Router#erase startup-config Router#enable Router#configure terminal Router(config)#interface FastEthernet 0/0 Router(config-if)#ip address 192.168.1.1 255.255.255.0 Router(config-if)#no shutdown Router(config)#interface fastEthernet 0/1 Router(config-if)#ip address 192.168.2.1 255.255.255.0 Router(config-if)#no shutdown Router#show ip interface brief Interface IP-Address OK? Method Status Protocol FastEthernet0/0 192.168.1.1 YES manual up down FastEthernet0/1 192.186.2.1 YES manual up down Vlan1 unassigned YES unset administratively down down
This should work but it doesn't . Any ideas? We also installed new firmware.
Solved! Go to Solution.

This solved the simple problem.
ip route 192.168.0.0 255.255.255.0 192.168.1.0
ip route 192.168.1.0 255.255.255.0 192.168.0.0
Thank You!

Hi @1885
What exactly is not working?
As per your config, you assigned IP address to two interface on the router, right. Two different network. This is correct for a router. Now, you router is able to pass traffic from network 192.168.1.0/25 to 192.168.2.0/24 and vice-versa.
What are you trying to accomplish from here?

This script did not work. I need to assume there is something wrong with the router.
Thanks for the lines.

Alright. Try to explain what is not work. I mean, are you trying to ping the router and it is not responding? What are you trying to do and is not working? Maybe I can help you if you explain the problem.

Hi
What is the purpose of your script? I see the changes have been applied, now the interfaces are up down it looks like a layer 2 problem, it could be cable or interface.
Could you please provide details about the objective of this configuration?
Thank you in advance.

Thank you for the post.
All we are trying to do is ping across router.
Right now we have the 2811 with level 1 switches on each side.
From node 192.168.1.2/24 to ndoe 192.168.2.2/24
We will not be able to work on this until Wdnesday 12/6/17
Thank You

I am the student in question, and there has been a (not so) slight change.
We (I) hooked up the router to the "real world" (the room), and i was able to ping everything on our network from the router's CLI interface. I also swapped routers and the router is definitely not the issue, somehow the data needs to go "through"the router.
The original (and current) set up is a few computers hooked up to a Cisco 24-port switch (we'll have to check the model tomorrow). Only one of the said computers is actually powered on, which is also the computer which i have hooked up via serial to the router's console port. The switch is not programmed but indeed works.
The switch is set up with a crossover cable going from GigabitEthernet 0/1 on the switch to FastEthernet 0/1, while the real world connection is on FastEthernet 0/0 on the 2811.
Hope this helps.

This solved the simple problem.
