Title:
  It takes too much time for L3 agent to make router active ( about 2
  minutes ).

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron juno series:
  Fix Committed

Bug description:
  It takes too much time  for L3 agent to make router active ( about 2 minutes ).
  This is especially not good for HA setups. 

  openstack-neutron-2014.2.1-5.el7ost.noarch
       
  Reproduced on non HA :
       
  1.openstack-service stop neutron-openvswitch-agent | openstack-service stop neutron-l3-agent |  openstack-service stop neutron-dhcp-agent
       
  2.neutron-netns-cleanup --config-file=/etc/neutron/neutron.conf --config-file=/etc/neutron/dhcp_agent.ini  --config-file=/etc/neutron/l3_agent.ini  --force > /var/log/neutron/l3-agent.log
       
  3.openstack-service start neutron-openvswitch-agent | openstack-service start neutron-l3-agent |  openstack-service start neutron-dhcp-agent
       
  4.wait until namespace is created.
