and I find the reason is that a ha vr_id is not allocated when l3 agent start to instance this ha router on the l3 agent node,that leads the ha router instance cat't get a keepalived instance through _get_keepalived_instance with ha vr_id.

Can you please share the following information:

1) What is the command you are using to create the router?

2) What version of Neutron are you working with?

3) What is your environment topology?

@shiliang - can you give the 'openstack router create...' command arguments you are using to create the router? And the version of neutron you are using? Thanks.
