Hey everyone,

I am a newbie and I am working on the ccna and am trying to build a simple network in packet tracer. I am hoping someone can point me in the right direction, I can't ping across the two routers. I believe my IP address's are correct and my subnet mask is correct. Its simple but I still can't get it. Thanks again

I apologize for not having a program that can open that at this time. (I have the packet tracer software somewhere, but nowhere handy to install.)

Could you please provide the following?
1 - which interface in routerA is connected to which interface of router B
2 - post the configuration of the interface from each router

Thanks.

Ok any help would be greatly appreciated

connecting interfaces are Fa 1/0 to Fa 0/0
This routerA
Interface IP-Address OK? Method Status Protocol

FastEthernet0/0 192.168.2.1 YES manual up up

FastEthernet1/0 192.168.1.49 YES manual up up

Serial2/0 unassigned YES unset administratively down down

Serial3/0 unassigned YES unset administratively down down

FastEthernet4/0 unassigned YES unset administratively down down

FastEthernet5/0 unassigned YES unset administratively down down
FastEthernet0/0 is up, line protocol is up (connected)
Internet address is 192.168.3.2/24

Router B



Interface IP-Address OK? Method Status Protocol

FastEthernet0/0 192.168.3.2 YES manual up up

FastEthernet1/0 192.168.2.47 YES manual up up

Serial2/0 unassigned YES unset administratively down down

Serial3/0 unassigned YES unset administratively down down

FastEthernet4/0 unassigned YES unset administratively down down




FastEthernet5/0 unassigned YES unset administratively down down

Looks like your layer 1 and 2 are ok, but layer 3 addressing is not correct.

Fa1/0 Rtr A - 192.168.1.49
Fa0/0 Rtr B - 192.168.3.2

Depending on your subnet mask of course, but if they are class C default subnet mask then they will not talk to eachother.

Ravenclaw

Actually they are class C masks, can you explain why that is?

They need to be in the same subnet to work. Do a show ip route on Rtr A, it would say 192.168.1.0 is connected via fa1/0, but won't have a route to 192.168.3.0.

Change Rtr B ip on Fa0/0 to 192.168.1.50 and it should work.

Your default gateway are wrong on the PC's

Here's what I found,
- The IP address & default gateway on PC0 is wrong. It needs to be in the same subnet as the Fa0/0 interface on Router0.
- You have a static route to 192.168.10.0 with a next hop of 170.168.1.254. There is no next-hop with that IP. The next hop address should be the Fa0/0 of Router2.
- There is no routing configured on Router2.

Sorry for the long pause I just finished my 12 hour shift. Thank you so much I finally got it to work. So just to be clear I need to make sure I understand these things are correct.

- Each router interface has to be in a different network but in the same subnet mask if they are connected to each other..
-any PC and the default gateway must be in the same IP range with the proper mask..
-you must have a static route to a network, from the interface of the next router interface (as the next hop)

Thanks again
