bird init state

[Tapio Haapala]

Hello,
Is this allready fixed on svn version?

With old bird we had problem that some times it leave ospf serrions to 
init state.
With 1.3.5 bird looks that there is still problem that if remote ospf 
peer get hanged "right way" (on this case guagga node) bird leave 
session to init state. Naturally this is quagga problem and routes behid 
that node is dead anyway. BUT looks that if any of ospf sessios are down 
it can disturb routes from other sessions on same interface. Other 
sessions on same interface go to 2way/other state and routes are lost 
also behind of them.

So if we have this kind configuration

rA ----- rB
              |
            SW
            /  \
netC-rC  rD - netB
                 |
                netA

And if session to rC hangs to init state it cause that rD go to 
2way/other and also routes to netB and netA are lost.

On normal state:
Router ID       Pri          State      DTime   Interface  Router IP
10.123.123.99     1         full/other  00:01   eth3       y.y.y.1
10.123.123.211    1         full/other  00:10   eth3       y.y.y.212
10.123.123.1      1         full/other  00:10   eth3       y.y.y.210
y.y.y.102    1         full/dr     00:10   eth3       y.y.y.102
x.x.x.253     1         full/other  00:10   eth3       y.y.y.17
c.c.c.5     1         full/dr     00:09   br70       z.z.z.226

On problem state:
Router ID       Pri          State      DTime   Interface  Router IP
10.123.123.211    1         2way/other  00:10   eth3       y.y.y.212
10.123.123.1      1         init/other  00:09   eth3       y.y.y.210
x.x.x.253     1         full/bdr    00:10   eth3       y.y.y.17
y.y.y.102    1         full/dr     00:10   eth3       y.y.y.102
10.123.123.99     1         2way/other  00:10   eth3       y.y.y.1
c.c.c.5     1         full/bdr    00:10   br70       z.z.z.226
