Yes, saw your thread on this and was suprised that this still was an issue
when i could get the other area subnet to be distributed in the network.
Followed your recommendation/workaround and the network was distributed,
but it didnt really solve my problem, that is to have several areas.

Ospf multiple areas not redistributing

[Roger Skjetlein]

Hi,


have an issue with ospfd when using multiple areas and networks from area
10.0.30.0 not distributed to 0.0.0.0.

eg

excerpt from config

area 0.0.0.0 {
 interface gre0
 interface gre1
}
area 10.0.30.0 {
 interface em0
}

the network for em0 is 10.0.30.0/24 and is never seen in ospf routing
table. Moving interface em0 to area 0.0.0.0 solves the distribution of the
network, but not having multiple areas.

OpenBSD 5.7/i386

please show more info, specifically ospfctl sh database, ospfctl sh rib 
from at least two routers in your network.

I also have the exact same issue and solved it by moving to area 0.0.0.0

Check out this thread

don't know it's current status and what happened with the patch.

hint: if you have a second ospf router on 10.0.30.0 area then the route 
is distributed.
