I still have a problem about the fg device with private ip address. In DVR mode, there is a external ip address in fq device, because we need to figure out the default route.
If the fg device with a private ip address, how do we figure out the default route in fip namespace? Default route is not reachable by the private ip address, doesn't it? Hopes for your reply. ;-) 2016-08-03 6:38 GMT+08:00 Carl Baldwin <c...@ecbaldwin.net>: > > > On Tue, Aug 2, 2016 at 6:15 AM, huangdenghui <hdh_1...@163.com> wrote: > >> 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.
