Routing Traffic locally

[UKDanny666]

Hi there,

Just starting out on my journey to become certified. Working through the pluralsite videos amongs other material.

Just got to the basic configuration of a cisco router segment, basically I am connecting two laptops to the fast ethernet ports of my cisco router.

interface FastEthernet0/0
 ip address 10.0.0.1 255.255.255.128
 duplex auto
 speed auto
!
interface FastEthernet0/1
 ip address 10.0.0.129 255.255.255.128
 duplex auto
 speed auto
!

Configured my end devices with a corresponding valid host address, and tried to ping each machine from oneanother.

Each machine can only hit their f/e ports, traffic does not seem to pass to the other network.

Appreciate this may be a small error compared to the other subject on here, but we all gotta start somewhere.

Thanks in advance

Danny

Hi,

Kindly verify the correct default gateway on both networks and disable the firewall on both machines (for temporary).

In addition to Deepak's suggestions, post the output of 'ipconfig /all' of both laptops...

Many thanks for the replies,

So on the laptop connected to fe0/0

Ip: 10.0.0.10

Sn 255.255.255.128

Dg: 10.0.0.1

laptop on fe 0/1

ip: 10.0.0.130

sn: 255.255.255.128

dg: 10.0.0.129

Both laptops have had f/walls disabled to no avail:( 

I’ve also tried using the ip routing command, just in case that’s disabled but again no success.

thanks again

Hi,

Is it a lab? 

Please share tracert command output from the windows machine. 

I think you are connected with some other connection as wifi at the same time on the lab system. If yes, then please disconnect the wifi or other connection to the lab system and test it again.

When I read the original post I believed that the most likely issue was firewalls on the PCs. If both PC firewall are disabled then we need to look for other issues. Can you post the output of these commands on the router

show ip interface brief

show arp

Additional questions:

- can each PC ping the router interface to which it connects?

- can the router ping each of the connected PCs?

Deepak,

Many thankyous

I left the WiFi on one of the laptops. All traffic routing, on what should have been a fairly straight forward lab.

Regards
