Hello
If you use OSPF in ver > 3.13 I have found on random links you need to manually set the “router-id” for it to work properly.
Just a heads up incase someone spends a day (like me) upgrading and downgrading with much stress to why OSPF stopped working
Apart from that I have found .16 very very good.

What kind of hardware are you using saying 3.16 is very good? Routerboard models versus x86?

Routerboards 4xx are the only ones I have tested.
Still sitting with 3.13 on my core router (x86 system), it will take some trust before I upgrade this again.
