your condition was only if one of the network is showing on the Routing
Table but you probebly overlooked that both networks are not in your routing
table from your verification
Verification
rack1r6(config)#int f0/1
rack1r6(config-if)#shut
rack1r6#sh ip route 150.1.1.0
% Subnet not in table
rack1r6(config)#int s0/0
rack1r6(config-if)#shut
rack1r6(config-if)#^Z
rack1r6#sh ip route 150.1.3.0
% Network not in table
can you show that the routes do apear on your routing table and you still do
not advertise the 0.0.0.0/0?
1) Make sure first the routes (150.1.3.0 or 150.1.1.0 ) are showing on your
RIB
2) do clear ip route * on SW1 to reinitialize the build of the RIB
3) If you still do not see the default route on SW1 then do debug ip rip on
R6 to make sure it is sending i, after you verified step 1.
