I think I have a problem with some OSPF routing.  I have a small
network setup (see attached image) which uses 2 OSPF areas, with 3
subnets.  I have a LAN subnet (192.168.10.0/23, Area 0.0.0.1) and a
DMZ subnet (172.20.0.0/23, Area 0.0.0.0) and a public subnet which is
not configured using OSPF.

I can connect and ping nodes from LAN <------> DMZ no problem and can
also ping from DMZ <-----> Public no problem.  But when I try to ping
and connect to machines within my own public range LAN  <-----> Public
I have some connectivity issues.  Pings will take a while and time
out, then eventually (2 - 10 seconds) it's like OSPF has figured how
to get there and they works.  If them hosts then have not been
contacted in a while since it started working, I have the ping and
connectivity problems again.

Does anyone have any idea where I might be going wrong here?

protocol config for the both internal routers below with respective
OSPF and routing tables.  If you need further information please let
me know.

Thank for the help.
