Thanks a lot Danny for your answers: So now : 1-which version of ODL SFC supports the NSH proxy ? Boron supports it ?
2- Regarding Openstack ,,, do you mean that the each VM host a NSH unaware SF should have the VPP based NSH proxy ? 3- where can I find the VPP based NSH proxy ? 4- The ODL controller will contact the VPP based NSH Proxy for what and when ? ( I think that the ODL controller should use the floating ips of the VMs hosting the SFs in order to be reachable from the ODL controller) Best regards, Ahmed On Wed, Aug 31, 2016 at 12:27 PM, Zhou, Danny <[email protected]> wrote: > Answers inline. > > > > *From:* [email protected] [mailto: > [email protected]] *On Behalf Of *Ahmed Medhat > *Sent:* Wednesday, August 31, 2016 6:08 PM > *To:* [email protected] > *Subject:* [sfc-dev] NSH Proxy for NSH unaware SFs > > > > Hi all, > > I would like to know the status of the NSH proxy ? and need to know some > more details about it please (How it works, How to configure it with ODL > SFC solution in Openstack, Where Can I found it ...etc) ? > > DZ: The patch https://git.opendaylight.org/gerrit/#/c/42699/ from Yi Yang > has been merged, which leverages NETCONF SB plugin to interface with VPP. > Integration test ongoing as sth is blocked on the Honeycomb agent.
