Neutron issue in current Xena Version of openstack

hi Team,

i am facing issue after installing XENA version of Openstack, where in the Same hosted Network node, some routers work, and some not, The real issue is the router which are not working, All floating IP assigned to the router does not work, but other routers hosted on same L3 agent Works

I am seeing this king of error " "Could not generate persistent MAC: No data" , but i am not sure this is impacting the issue
