The question was asking why the RIP statements did not match the actual branch networks exactly. Why are they different.  The route statement that routes traffic to R2 does not list each advertised network that R2 is directly connected to.

RIPv1 is a classlfull routing protocol, meaning it does not send the subnet mask with updates. So the and .64 are assumed to be Class C subnets and the route is sent out as network as the "Sh route" states.

Make sense.

Now if R2 was using RIPv2 (Classless) then the actual subnet mask would also be sent in the routing update and "Sh route" would show both routes
