The adjacency issue is solved.  We were hoping to use the Debian Zebra
package because we like their package management so much, but they do tend
to be behind the development curve.  When we built Zebra from the current
source the adjacency issue just went away.

Next question.  Now that the adjacency issue is solved, the router that is
in both area 51 and area 0 is learning routes from area 0, and the other
router in area 51 is then learning those routes in turn.

If I add a route on the area 51 only router, however, that route shows up
on the router in both area 51 and area 0, but does not show up on the
other routers in area 0.  I am using all the redistrute commands I can
find.  I'm baffled at this point.  Any insight would be appreciated.
