Fixed In Version:
Doc Type: Known Issue
Doc Text:
Currently, when MTUs mismatch, the communicating peers are unaware of the discrepancy, and the Networking service (neutron) can silently drop the packets. OVN is the cause of this problem because it fails to emit the message, `ICMP Fragmentation Needed`. *Workaround:* the preferred method is to adjust the MTU value to prevent packets that are too large from being transmitted. An alternative method is to set the `OVNEmitNeedToFrag` option in the tripleo templates. For more information, see the Knowledgebase solution, link:https://access.redhat.com/solutions/7092922[Neutron ML2/OVN packet fragmentation problems].

Comment 2 Greg Rakauskas 2024-10-31 14:03:35 UTC 
Hi,

This BZ was cloned from BZ 2314429 because we need a Target Milestone = z4 to
include the Doc Text as a known issue in the RHOSP 17.1.4 Release Notes.

Best,
--Greg R.
