Here is why it is not working;
You ethernet inteface to R1 is class C /24 by default 192.168.1.0/24.
The Loopbacks are /28 being summarized into class C /24, but the network
classful address is 172.16.0.0 or class B /16. Rip will only accept /24
routes from a neighbor if the Network is a class C network 192-223 OR -> if
the interface is a different class (say 10.1.1.1/24) but has a class C (/24)
mask -> then other 10.1.x.x/24 will be sent.
The ethernet interface to R1 is 192 or class C by default, so only classfull
addresses will be sent to the neighbor ..i.e. 172.16.0.0/16 NOT
172.16.1.0/24. You have to summarize to /16 or give the ethernet interface a
172.16.x.x/24 address.
