neutron vrrp ha still do not support conntrack feature now.

1, Setting up test environment
# bzr branch lp:~openstack-charmers/+junk/openstack-charm-testing
juju destroy-environment --force zhhuabj
juju switch zhhuabj && juju bootstrap
juju-deployer -c ./next.yaml -d trusty-kilo
juju add-unit neutron-gateway
juju set neutron-api overlay-network-type=vxlan
juju set neutron-api l2-population=false enable-l3ha=true
./configure #edit script to use vxlan
source ./novarc
neutron net-list && neutron router-list
nova boot --image trusty --nic net-id=98e10e32-13eb-48ee-b265-4ae0e449b6e5 --flavor 2 i1
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
nova floating-ip-create
nova floating-ip-associate i1 10.5.150.1

Some important configurations in neutron.conf are as below:
l3_ha = True
max_l3_agents_per_router = 2
min_l3_agents_per_router = 2
allow_automatic_l3agent_failover = False

2, Future Work & Limitations
http://assafmuller.com/2014/08/16/layer-3-high-availability/
http://blog.aaronorosen.com/implementing-high-availability-instances-with-neutron-using-vrrp/

TCP connection tracking – With the current implementation, TCP sessions are broken on failover. The idea is to use conntrackd in order to replicate the session states across HA routers, so that when the failover finishes, TCP sessions will continue where they left off.
Where is the master instance hosted? As it is now it is impossible for the admin to know which network node is hosting the master instance of a HA router. The plan is for the agents to report this information and for the server to expose it via the API.
Evacuating an agent – Ideally bringing down a node for maintenance should cause all of the HA router instances on said node to relinquish their master states, speeding up the failover process.
Notifying L2pop of VIP movements – Consider the IP/MAC of the router on a tenant network. Only the master instance will actually have the IP configured, but the same Neutron port and same MAC will show up on all participating network nodes. This might have adverse effects on the L2pop mechanism driver, as it expects a MAC address in a single location in the network. The plan to solve this deficiency is to send an RPC message from the agent whenever it detects a VRRP state change, so that when a router becomes the master, the controller is notified, which can then update the L2pop state.
FW, VPN and LB as a service integration. Both DVR and L3 HA have issues integrating with the advanced services, and a more serious look will be taken during the Kilo cycle.
One HA network per tenant. This implies a limit of 255 HA routers per tenant, as each router takes up a VRID, and the VRRP protocol allows 255 distinct VRID values in a single broadcast domain.
