OSPF fails to redistribute default route after a reboot

I have 10 MT routerboards participating in OSPF in a ring configuration. The Gateway router (GW) redistributes default as Type 1 and the other 9 get their default from the GW Router. If I reboot the GW router, OSPF routes continue to propogate throughout but the neighbors lose and do not get back their default from the GW router unless I disable the networks on the GW router's OSPF configuration and then reenable. I have confirmed this behavior with another local ISP running MT and they ar seeing the same thing. I am runing the routing package, not routing-test.

As far as I know, you must using routing-test for stable OSPF.

OSPF is not stable

Hi,

I´ve reported a Bug where Ospf looses neighbors and even reboot does
not help. (2.9.42 routing and routing-test). So you cant depend on it.
I`ve found myself testing and inserting static routes the whole night with
a broken network.
So be aware Ospf Implementation is beta quality at the moment.

have you tried with M/T ROS v3beta7?

Yep - Unfortunately we have seen the same - using OSPF but with static routes on all routers.

OSPF is just not stable at all...

Normis, can you confirm that:

1. OSPF is not stable -or-
2. We should be using routing-test?

BTW: I too keep static defaults in place and disabled for just such an occasion.

I would like to add that I have a network of 10 MT routers. I have also noticed that OSPF does not appear to be stable. The most notable issue is under neighbors, it stays at Init. I tried routing-test in the past and did not see any improvement. I should probably try it again before I contact support.

I have been tempted to make a suppout and send it to them for help. I have never used there tech support, anyone have any good coments on them?

No. It's a production network. I act as conservative as I can
as I get a lot of angry people on the phone.

RIP working?

Anyone tried RIP with more than 10 MTs?

You must use routing-test for sure. Any bugs in routing are fixed only in routing-test package. Don't be afraid of "test" it doesn't mean that this package is only for testing

Yes, routing-test is more advanced, but my problem exists on both
routing and routing-test..May be it has nothing to do with both. Multicast
packets do not reach the neighbors and this is what Ospf depends on.

Add another that has seen the same thing with default static not getting redistributed on a reboot. It doesn't happen every time.

I have same problem too, use 2.9.42

After the routerboard reboot, the cisco cannot connect the mikrotik OSPF.
