Router A need not receive the routing information sent by other routers but the 
change of topology in the internal network should be broadcasted to other 
routers in time. To implement this, the interface through which router A connects 
to the Internet can be configured to send but not receive the RIP packets.

The Ethernet interfaces of routers A, B and C are interconnected. Router A 
(192.1.1.1) only sends RIP packets, but does not receive the RIP packets 
broadcasted by router B (192.1.1.2) and router C (192.1.1.3).
