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.
