I created a line of routers  R5---R1---R3-----R2   ( that's the way the test
pod I was using is set up )

There are loopbacks on R5 and R2 that are addressed and will become the
default networks

R5 and R2 contain the statement ip default-network.

R5 contained the 100.x.x.x/24  and the 199.1.1.x /24 nets

R2 contained the 135.35.x.x/24 and the 155.55.x.x/16 nets.

R3 was where the routing table outputs were taken. The default network was
propagated properly and as expected only for those default nets that were
also classful.

Again, my point is that there appears to be an issue with flagging the major
network when all you have are subnets. I did not try advertising  EIGRP
summaries from R5 or R2. That might work too.
