OSPF loading State

[Ryan Whelan]

I have 2 linux machines connected to one another over the internet via
a IPSec protected GRE tunnel.  Each of them are running OSPF from bird
1.3.2.

The issue is that one of them will not fully peer with the other,
unless the other is started after the one with the issue.  Is just
stays in state 'loading' while the other machine will be in state
'full'.  In other words, node 2 will only go to state 'full' if node 1
is started after node 2. If node 2 is started after node 1, it will
sit in state 'loading' forever. Node 1 has no issues.

Here is a log from the node that is failing to sync up (node 2):
