My experience is that has almost always been a configuration error.
Often related to Router ID, but not necessarily the one reporting the
errors.
One thing MT appears to not like is Router ID of 0.0.0.0.
Duplicate IP addresses can cause this message. The packet actually came
from somewhere else, but looks like it is local.
I am sure there are some other common things, but it has been a while
since I was dealing with this error message.

Some of our routers report this same "locally originated" OSPF message
every few minutes. It's nothing close to "blowing up" the logs, but
troubling nonetheless. And yes, it didn't start happening until we
upgraded, probably to 6.36.x. Just another data point.

Yeah, that's how we have it set. Each router has a unique router ID. Our
main router has one ID, but has a dozen or so ospf neighbors. We've been
running this setup for quite a while. Doesn't seem like we saw it until an
upgrade a while back. We do have a loop in our network, on purpose, that
OSPF routes around for primary and redundant. However, all of the IP's that
are showing in the logs aren't part of the ring. They are all legs/stubs of
the ospf, not anything to do with the ring.

typically, best practice, is to take an IP Address (unique) and assign it
to the Loopback interface ( a dummy bridge interface) and use that a router
id in your OSPF instance..
irrespective of how many interfaces you have running OSPF, only one unique
router id is required.
---------
is it possible that you have created a loop where you are seeing the
packets from the router it-self ?

Subject: Re: [Mikrotik Users] OSPF errors on router
I saw this issue pop up again. The duplicate router ID thing caught me.
We've got a main tower that has a vlan to a dozen other sites, each
running an MT with OSPF. Each vlan has a ptp ospf interface, not broadcast,
with a unique /30 public IP space. We only run one instance of OSPF on our
main tower router, with only one router ID.
I'm thinking maybe the one router ID across all the vlans is causing the
issue? Functionally, everything is working fine. But our logs are blowing up
with the "Discarding packet: locally originated" error.

Some things to make sure of before banging your head.
1.Make sure *every* router participating in OSPF is on the same OS
version. They don’t have to be the latest greatest, just the same. one
router in a pool of 50 can taint the database. Even if it’s one version
behind of ahead.
2.Make sure your loopback IP addresses (you are using loopbacks correct?)
are listed as the router ID.
3.If these are true point-to-point backhauls change the OSPF type to PTP.
This cuts down on the chatter on the link. Once OSPF establishes a session
it stops talking as much as if it were in broadcast mode.
4.Double check your IPs and subnet masks.
80some% of the OSPF issues I see are a result of mismatched router OS
versions. Bringing everything to the same version solves a ton of issues.

Not completely. Not sure we don’t have a small Comm issue to a backhaul.
However the outages have gone away just get 2-3 errors a day but it is not
causing any OSPF issues or outages. Thinking of just adding a Filter rule
to block them and go on with life.

Subject: [Mikrotik Users] OSPF errors on router
I am getting the attached errors in my event log on one tower. No ports
are flapping on the backhaul. Both Mikrotiks are on 6.29. Both routers CPU
is <10%. As soon as this error passes they will work 100% for hours, even
days. I am confused and lost. PTP conection was Broadcast and have changed
to point to point. What to look at?
