I believe my issue is related to xos0053644, but info on that specific issue seems to be limited to https://gtacknowledge.extremenetworks.com/articles/Solution/Local-multicast-224-0-0-x-packet-loss
no mention in release notes etc. Unless i'm missing a way to search bulk release notes/version history for bug numbers.
Also not 100% sure this is the issue, we do seem to have issues periodically with OSPF at some sites, but i'm unsure which of my switches is the root cause.
Our layout is
Remote Site Switch (ospf x450/x460-g2 etc) -> FIBER -> MLAG-Aggregation (l2-transit x670) -> FIBER -> MLAG-Core switches (ospf x670-g2)
The one page I found says "temporary/short outages" on ospf but honestly we've seen outages of many hours or days on ospf for some sites, and it doesn't happen to all the sites.
Should i just disable the to-cpu on all ports of our aggregation switches? Is their a draw back to doing that if those switches are only qinq and vlans no l3 beyond inband management ip? Can i do the commands on a live network or will it affect traffic flow on the transit switch?
I'm having issues understanding the problem, theirs 4 solutions listed but no explanation really of figuring out which switches are the issue actually, or what the draw back is to each of the solutions
None of the options seem to be for running on the actual OSPF switch (the ones with the ip interfaces) so is the issue only on switches that are layer 2 transit switches?
