Hi i tried using ospf v2 on routeros 3.30 but got alot of packet disgarding errors in the logs, so i upgraded to version 4.6 and the problem disappeared. I do get minor error that says “link state changed from attemp to down”
Now i would like to know what routeros version does the people that uses ospf v2 recommend?
Which one works best for them?
is the link wireless?
Yes
have you set up NBMA neighbours? http://wiki.mikrotik.com/wiki/Manual:OSPF-examples
Yes it was a bit tricky, i managed to set it up.
But two days after that i had to move back to static routes again becos on router 1 it created a gateway to another router and not the router that gives internet.
wrong setup = wrong routes 
Could be, i have setup 3 static gateway with routing marks. I also see that on some of my routers is does not create a gateway so i has to make the gateway static.
I have setup ospf again and so far it is working good. i have disabled my static routes incase i need to enable them.
Im going to test it for a week or so and if it works then i will use it.
Make sure all your OS versions are the same level. This helps quite a bit.
