Comment 3 ying xu 2023-03-07 07:40:15 UTC 
reproduced on version:
ovn22.09-22.09.0-46.el9fdp.x86_64
ovn22.09-central-22.09.0-46.el9fdp.x86_64
ovn22.09-host-22.09.0-46.el9fdp.x86_64


and verified on version:
ovn22.12-22.12.0-20.el9fdp.x86_64
ovn22.12-central-22.12.0-20.el9fdp.x86_64
ovn22.12-host-22.12.0-20.el9fdp.x86_64



topo as below:
                          system1                                                                                  system2
server0-------ls1----------lr1-----public------------br-ext------------br-ext--------pulic-----------lr2---------ls2--------client
and set LB on lr1(enabled reject=true), dnat and snat on lr2. and set mtu=500 on lr2.


I start connection between server and client,
send big packet to client.
then I can see lr2 send icmp unreachable packets to lb vip.

on old version:
big packets not pass

on fixed version:
big packets pass
