Hello,
I am learning and reading the CCNA / CCENT books , just to understand how it works. (It is only the second week I have the routers to play with)
At the moment I was able to connect Router1 via F0/0 to my ISP and F0/1 to my computer via DHCP , and it works I have INTERNET on the computer connected on F0/1.
The next step I would like to archive is to connect my second router to one of the S0/0 S0/1 busses and connect the computer to F0/0 of this router.
I can ping the S0/0 and F0/0 and even the computer that is connected on the first router , but nothing from the internet (even 8.8.8.8 GOOGLE DNS done not work)
NOTE:
ROUTER 1 = 2621XM + WIC2T (DTE)
ROUTER 2 = 2610XM + WIC1T (DCE)
Here bellow what I did on Router1 :

Hi Didier,
You have a static route on router 2 (ip route 10.0.100.0 255.255.255.0 172.16.0.1)
this static route will give you readability to subnet 10.0.100,0/24 only
so in order to have readability to the world you need to change your static route to a default route as follows:
ip route 0.0.0.0 0.0.0.0 172.16.0.1
then test again
