It is normal for it to be in 2-way adjacency  with with all the routers in
area 0 _except_ the DR and BDR.  Indeed, my Zebra forms a 2-way adjacency
with all the routers in area 0, except DR and BDR, but it never even makes
it to 2-way adjacency with the DR and BDR, let alone the full adjacency
needed for the Zebra box to receive and inject routes into the OSPF
routing table.

Thanks for the link.  Good info, even though not the answer to this
problem.

Thanks,
