Are you restricted to using only 150.100? The reason I ask is that if you
are injecting a default so that IGRP can get to the VLSM subnets within
OSPF, the only way I am aware of is to set "ip default-network" on the ASBR.
And as you have noted, this has to be classful or it will set a static route
like you noted. Can you configure another non 150.100 network to a
loopback, propogate through ospf, redistribute through igrp, so that R6 sees
a classful network?
