Help with Lab Setup

lex0429

Im trying to mimic a virtual lab on actual equipment. My goal is using RIP, i want to ping one host from the other.
I have two 1760 routers each with a T1 DSU/CSU card. They are connected together via those cards with a T1 crossover cable, the S0 ports. Attached to each routers FA0 port is a computer via cross over cables.

Here is a pdf diagram of the setup.. http://www.mediafire.com/?5dvtciugf29
Here is what i can do,
-Cairo can ping 192.168.2.2 (other routers Ser port)
-Cairo can ping 192.168.3.1 (other routers FA port)
-Amman can ping 192.168.2.1 (other routers Ser port)
-Amman can ping 192.168.1.1 (other routers FA port)
-192.168.1.2, host connected to Cairos FA port, can not ping Cairos Ser port or the other router or the other PC
-192.168.3.2, host connected to Amman's FA port, can not ping Amman's Ser port or the other router or the other PC...


Here are the configs...

Any help would be appreciated..Everything looks good as far as i can tell

First thing I noticed but this probably isn't the issue...where is the "clock rate 64000" command on one of the serial interfaces which you've designated as your DCE?

Also, please go into your host IP settings and let us know what you've set your default gateway as on each machine. The default gateway on each host should be the IP address of the e0 interface on the router that it is connected to.

Can you ping from the host to the IP address of the e0 interface of its connecting router?

Also, if the hosts connected to the routers are Windows XP machines with SP2, the firewall could be enabled and it blocks ping by default.

First off thank you very much for your quick response. You were exactly right, the DG's were screwed up..quick change and working like a charm

Im assuming that in my situation the "Amman" router would be the DCE, correct?

With only 2 routers I dont think it'd matter which one you made the DCE. But in any case it's working now so...good stuff.

Thanks again

1 more thing, if instead of using RIP i used static routes what would they be?
Here is what i tried with no success

on Cairo
ip route 192.168.3.0 255.255.255.0 192.168.2.2


on amman
ip route 192.168.3.0 255.255.255.0 192.168.2.1

This is wrong.
Correct is:

ip route 192.168.1.0 255.255.255.0 192.168.2.1

net 192.168.3.0 is already attached to router amman and do not need a static route to reach it.

my mistake, thats what i had in my config, typo..that would get me access from one host to the other?
