Stealing routes from a Cisco router

Your mission (if you decide to accept it) is to steal all routes from R2, The two things that you know is that R2 is using RIP without authentication at all

Happy hacking :-)

The only way R1 and R2 will share routes is if they are on the same subnet

You know nothing about R2, it is just a black box

In this case you must use the command "no validate-update-source" under the RIP process. This will stop R1 checking if the source address which send the updates is in the same subnet

R1
router rip
 no validate-update-source
 network 10.0.0.0
 network 192.168.0.0

R2
router rip
 network 5.0.0.0
 network 6.0.0.0


The end result:

show ip route rip
R     6.0.0.0/8 [120/1] via 5.5.5.5, 00:00:01
