Time synchronization ranks up at the top as well. Doesn't usually cause
OPs error, but it is critical.

Just wanted to echo and reinforce the comments that Justin Wilson made about
every router that participates in OSPF needs to have the exact same version on
it. He is 110% correct. This is not brought up a lot but is the SINGLE biggest
factor in achieving OSPF and overall stability between the routers. I probably
have this conversation at least once a day with a client WISP about setting a
common version between all the OSPF routers.
The bugfix versions are good, I usually recommend 6.32.4 or 6.36.4 bugfix for
production routers and never the latest unless there is a feature or fix you
must have.

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?
