It looks like there is an Authentication Type mismatch. .13 is set to
none whereas .14 is set to MD5.

Good evening.
We had this happen when we reloaded a router at an active site
after a dhcp issue, and we are in the process of bring up a new
site and figured we would try it on a fresh router without any
risk of bringing a customer down.
We loaded the router with 1.7, as this is the production firmware
we are running across all routers in our network presently.
Completed config, ospf is working everything is behaving as
expected. Backup config and then loaded 1.8.5. As soon as router
reboots, it is no longer accessible. From the next router in
line, i can ping public interface of new router, but cannot do
anything else(This most likely due to firewall rules we have in
place). Router is online, but ospf is no longer working. It is no
longer listed as a registered neighbor and in fact appears that
ospf is turned off as a whole.
Last time we did this on the production router, it was available
locally but ospf did not work. It appears this is the case here
as well. Any help would be greatly appreciated as we need to
upgrade our entire infrastructure to take advantage of the MPLS
configurations for an upcoming project for a customer. Thank you
in advance!
So to further this, i am working at the site and trying to resolve
this, so far to no end.
Here is th ospf database:

No idea why this isnt working.
Also checked ps aux and it shows:
root 2126 0.0 0.1 6932 2872 ? Ss 16:02 0:00 /usr/sbin/ospfd -d -P 0
This thing is just dead in the water...
Any help or guidance would be greatly appreciated. Thank you.
