Hai
unless r1 and r2 is running rip ver 2 , u will not ba able to
achive this. The reason is r1 is no way aware of the subnet mask information
of that route ( Rip v1 will not send subnet mask information ). So its r2
itself will summarize to its major boundry and send it .. so 160 class B
network u will get is as /16 and 192 class c get it as /24
