in most text books a classful network is defined as a setup where all networks have same subnet mask. but when configuring rip, the classful is described as a network using default subnet mask. Rip does not advertise subnet masks. It is said the receiving interface on the router configured with rip assumes the same subnet mask on all the receiving networks. but how is the router able to receive some class B networks and class C networks and able to route with no issues. the receiving int subnet mask is /16. the networks received in advert are 192.168.1.0 , 192.168.2.0 uptil 192.168.10.0 on the same interface. if it takes the sm on them as /16, how is the router able to route the packets correctly. someone help me with clear definitions of classful network and classful routing and the differences between them please
I have this problem too.
