Is Area 20 connected to Area 0 via a virtual link??
If so, you have to configure the ABR that is connected to Area 20 and the
virtual link with Area 0 authentication, even though area 0 doesn't exist on
that router.
Kind regards,

Subject: OSPF not inserting route into route table.
Here is the problem i have, once i enable area 0 authentication i seem to
loose connectivity with Area20 (lo1, s0) on R5 from the rest of the network.
below is all the outputs and configs i ould think usefull. everything
appears up and I see the networks in the database but it is not being seen
in the route table. I have reloaded several times the routers each seperatly
and together. However this link is not being seen. Any suggestions.
Also as a side issue why would a network be in the database table but not in
the route table. I have not been able to find a link that indicates what
checks OSPF does prior to inserting routers into the route table (similar to
how eigrp and BGP will do prechecks)
Thanks in advance.
