Hi Carl
Thanks for reply. I was wondering how this works? fg device has one private
ip address, and the interface on upstream router has two ip address, one is
private ip address, and the other one is public ip address, Can fg device do
arp proxy for this situation?

hi john and brain
thanks for your information, if we get patch[1],patch[2] merged,then fg can
allocate private ip address. after that, we need consider floating ip
dataplane, in current dvr implementation, fg is used to reachment testing for
floating ip, now,with subnet types bp,fg has different subnet than floating ip
address, from fg'subnet gateway point view, to reach floating ip, it need a
routes entry, destination is some floating ip address, fg'ip address is the
nexthop, and this routes entry need be populated at the event of floating ip
creating, deleting when floating ip is dissociated. any comments?
The fg device will still do proxy arp for the floating ip to other devices on
the external network. This will be part of our testing. The upstream router
should still have an on-link route on the network to the floating ip subnet.
IOW, you shouldn't replace the floating ip subnet with the private fg subnet on
the upstream router. You should add the new subnet to the already existing ones
and the router should have an additional IP address on the new subnet to be
used as the gateway address for north-bound traffic.
