Description Slawek Kaplonski 2021-05-24 09:33:59 UTC 
+++ This bug was initially created as a clone of Bug #1960629 +++

In the DVR routers, neutron-server needs to populate ARP entries also for IPs added to the ports as allowed address pairs. When e.g. new IP is added to the allowed address pairs of the port, it works fine and neutron server sends notification about such new arp entry to the all L3 agents where dvr router is placed.

But in case when new vm plugged to the same router is spawned on completly new compute, or existing vm is migrated to the new compute where dvr router wasn't created before, arp entries for allowed address pairs aren't populated at all.

Hi Team,

Could you please let me know when this will be available for OSP13?

Seems the latest version in the repos is `openstack-neutron-12.1.1-42.el7ost.noarch` VS the fixed in version of `openstack-neutron-12.1.1-44.el7ost`

I know OSP13 is EOL but I assumed there was going to be one more release for bug fixes like this one. 

Thank you.
