I overlooked that. Maybe the default route is being deliberately
filtered at the backbone, you know you really do not have that much
control over the backbone. You might have to employ some other means
to have full reachability to those BB routes. If you have access to
the backbone check to make sure that ISIS default is not being
filtered.
Another area to explore is isis metric style, check isis issues with
metric styles, wide, narrow and transition.
