Well, maybe it doesn't! It is however required by RFC1158 #2 to advitice
the entire route table which include directly connected networks.
If your network was not a Serial but maybe an ethernet or tokenring, more
than one IP subnet could appear on each physical net. If not all hosts
without default gw (ie running routed) and all routers is aware of all
nets, the router(s) will need to route between different subnet on the
same physical net.
