Description of problem: Deploy RHOSP7 with 7.2 image on three controller. Enable L3_HA on all three controllers. Create a new tenant/router, and set gateway (gateway must be set first) Create two network, and attach to router ping from host to external network is not working. External gateway must be cleared and re-set to show the gateway is updated. When L3_HA is triggered (by bringing down the active router portgroup), endpoint is still pointing to the previous active controller for external gateway Version-Release number of selected component (if applicable): 7.2 How reproducible: 100% Steps to Reproduce: 1. Create tenant/router and set external gateway 2. Create network and attached to router, ping to external is not working 3. Trigger L3 HA failover, neutron port-show on external gateway still points to previous active controller Actual results: Expected results: Additional info: [root@c5220-01 stack]# neutron router-show

It sounds like the binding:host_id field for the gateway port is not being updated correctly to point to the node with the active router replica. Can you confirm that you have the fix for https://bugzilla.redhat.com/show_bug.cgi?id=1253953? The fix is in the following package and newer versions: openstack-neutron-2015.1.2-1.el7ost
