After Xena Upgrade it is self resolving. No more l3 agent restart is required.
The resolve times:
30 seconds for a compute which has 3 instances (kernel: 5.4.0-150-generic)
2 seconds for a compute which has 6 instances. (kernel: 5.4.0-90-generic)
ovs-vswitchd logs are attached.
Environment Details:
Openstack Version: Xena (cluster installed via kolla-ansible)
OS Version: Ubuntu 20.04.2 LTS Hosts. (Controller+Network Node Kernel:5.4.0-90-generic | Compute Nodes: Mixed 5.4.0-90-generic and 5.4.0-150-generic)
Neutron Version: 19.4.1.dev106 ["neutron-server", "neutron-dhcp-agent", "neutron-openvswitch-agent", "neutron-l3-agent", "neutron-bgp-dragent", "neutron-metadata-agent"]
There exist 5 controller+network node.
OpenvSwitch used in DVR mode and router HA is disabled. (l3_ha = false)
We are using a single centralized neutron router for connecting all tenant networks to provider network.
We are using bgp_dragent to announce unique tenant networks.
Tenant network type: vxlan
External network type: vlan
