floating-ip is implemented by doing 1:1 on the destination compute node.

/32 routes for each floating-ip are advertised to the DC gateway (an appliance 
or a software gateway); The DC gateway forwards
the packets through the overlay to the destination compute node; the vrouter 
kernel module on the compute node then performs 1:1 NAT. The gateway is 
stateless.

Hi all,

    As we know in neutron built-in implementation,
it does 1:1 NAT in router. Can someone give me some information about how 
opencontrail implements floating ip logical object of neutron?
