Hello Team,
I need a hint , where to check, as often my floating IP are not reachable in Openstack , it uses OVS based networking , and most of the time if i changed the l3 agent router it start working, I can ping the gateway from the qrouter namespace but can not ping the actual floating IP

First of all You need to know what type of router are You using: DVR, DVR-HA, HA or Legacy. Depending on that You can look in different places why FIP is not working. For HA or Legacy type, please start pinging FIP from outside and try to check, e.g. with tcpdump if packets are visible in qrouter namespace on qg- and qr- interfaces. If that is correct, try to check if You can ping Your fixed IP address from that qrouter namespace. With that test You should be able to figure out if problem is somewhere in the external network (the one from which FIP is) or the tenant network. For DVR routers, test should be similar but there is also fip- namespace on the compute node and You should start checking there. Details about different scenarios are also described in the https://docs.openstack.org/ neutron/latest/admin/deploy-ovs.html[1] - maybe that will be useful for You. -- Slawek Kaplonski Principal Software Engineer Red Hat -------- [1] https://docs.openstack.org/neutron/latest/admin/deploy-ovs.html
