James,
RIP is not one of those protocols. The behaviour you mentioned can be seen
with protocols that treat secondary addresses as stub networks eg OSPF. OSPF
will not send Hellos on secondary networks, will not form adjacencies on
secondary networks and will not even advertise secondary addresses/networks
if OSPF is not running on the primary interface.
But RIP will work fine with Secondary addresses. If you have Doyle's Routing
TCP/IP vol 1, check pages 526, 530 and 531.
I am setuping this up in my home lab at the moment and will paste results.
Thanks
