Hello Michel
There are a couple of differences between your output and the output of the lesson. In the lesson, the IOS version that is being used is 15.X while the version that you are using seems to be 12.X. I know this because in IOS versions of 15.0 and later, a directly connected network will produce two entries in the routing table, one marked “L” and another marked “C”. Older version show only the “C” like in your output. The “L” appears as a host address (/32) referring to the interface itself. This doesn’t really change anything as far as configurations go, it’s just one more entry that appears.
Secondly, the order that the routes appear in are slightly different. Some IOS versions put them in order of type or in ascending order of the actual address.
The above two don’t change the actual functionality, they just change the way that the routing table is displayed.
Finally, in your output, you have two routes advertised by RIP. These routes are:
2.0.0.0/8 and 3.0.0.0/8. It seems that you have advertised the classful routes (which gives a /8 prefix) rather than the /24 route which is indicated in the lesson. In order to get similar results to the lesson you must:
- Make sure you have assigned the correct subnet mask to the loopback interfaces on R2 and R3.
- Make sure that you have enabled RIP version 2 on all routers, which supports classless IP address scheme.
Once you do that you should get the /24 in your RIP learned routes. For more information about this, take a look at the following lesson:
I hope this has been helpful!
