deploy simple neutron gre env

start a vm
VM is pingable from qrouter namespace

associate floating ip using neutron client with corresponding port of the VM

expected result:

qrouter namespace has floating ip assigned to qg-* interface and VM is reachable

actual result:

look into qrouter namespace: there are no NAT rules, no ip addresses assigned to the qg-* interface. vm is unreachable

restart l3 agent. ip is finally assigned to qg interface, VM is pingable.

the problem is report interval is twice time bigger than agent_down_time, that's why server is not considering them as alive

    Specify report interval for neutron configuration

    Set report interval to 5 seconds which is 3 times
    lower than agent_down_time or it may lead to
    agent status flapping and neutron server not
    communicating with agents
