Ospf not working!

It seems to me that this is a bug, since with quagga and the old version of frr everything worked.

If I am reading this right router2 should be redistributing static routes to router1. Is this what you expect @ne-vlezay80 ?

dslicenc commented 7 years ago

Would it be possible to supply the output of "show ip ospf database external" from both routers? Also please supply the output of "show ip ospf neighbor"

ne-vlezay80 commented 7 years ago

Дело в том, что на quagga подобная схема работала нормально.

dslicenc commented 7 years ago

"The fact is that on a quagga this circuit worked fine."

That doesn't help me know what is not working. If you wish us to try to resolve the issue, then additional information is required. I've set up a very similar config in my lab and it works just fine redistributing static routes into ospf and advertising to a peer.
