Hello, Dina, Currently EVPN L2 networking has not started to design and implemented yet. Currently only shared VLAN L2 networking was supported, and is discussing VxLAN based L2 networking across OpenStack.
If there are EVPN networking contributors, we can put it into agenda and set priority. Could you help review this patch https://review.openstack.org/#/c/396564/, to see if the L2/L3 networking can meet your demand? Best Regards Chaoyi Huang ( Joe Huang ) From: dina....@orange.com [mailto:dina....@orange.com] Sent: Wednesday, November 23, 2016 7:04 PM To: joehuang; openstack-dev Subject: RE: [openstack-dev][tricircle]Questions about Tricircle L2 and L3 implementation Hello Chaoyi, Thanks for your answer. Related to Route Target parameter (RT) : I referred to the figure displaying pods interconnection through an E-VPN L2 network ("Tricircle in a nutshell" presentation). My question is : how are there populated and/or exchanged through the E-VPN interconnection ? Thanks, Best Regards, Dina De : joehuang [mailto:joehu...@huawei.com] Envoyé : mercredi 23 novembre 2016 04:20 À : SOL Dina IMT/OLN; openstack-dev Objet : RE: [openstack-dev][tricircle]Questions about Tricircle L2 and L3 implementation Hello, Dina, Thank you for your comments, it'll be good to discuss tricircle related topic in openstack-dev so that more people can be involved in if necessary, and keep the project transparent. So I copied the reply to openstack-dev@lists.openstack.org<mailto:openstack-dev@lists.openstack.org>. For L2VxLAN, the VNI identifiers will be allocated in central Neutron, and then same VNI segment will be used for local Neutron during get_network or get_port from Nova, the local plugin in local Neutron will query the network segment info. and persist same uuid and VNI in local Neutron. But VxLAN based cross Neutron L2 networking has not started yet, the spec has not submitted for review yet, currently only VLAN based L2/L3 networking were implemented, supported features could be found in the release notes:https://github.com/openstack/tricircle/blob/master/releasenotes/notes/initial-release-notes.yaml . VxLAN L2 networking and VxLAN as the bridge network for L3 networking will rely on the patch for "formalize the tunnel termination point by adding it to the port binding data model" which is mentioned in "Eliminating L2pop as a mechanism driver" http://lists.openstack.org/pipermail/openstack-dev/2016-November/107061.html Before VxLAN L2 networking and VxLAN as the bridge network for L3 networking, this spec is being reviewed, https://review.openstack.org/#/c/396564/, please join the review to see whether it can meet your demands, especially for the cross Neutron networking models. What is "RT parameters"? Tricircle supported L3 networking based on shared VLAN bridge network, you can refer to "6.6 L3 Networking across Neutron", but just as what mentioned in the release notes, only VLAN L2 network and shared VLAN as the bridge network for L3 networking are supported. There are todo list for the usage documentation in ocata release, you are welcome to join the contribution, no matter documentation or source code or review. Best Regards Chaoyi Huang (joehuang) ________________________________ From: dina....@orange.com<mailto:dina....@orange.com> [dina....@orange.com] Sent: 22 November 2016 21:54 To: joehuang Subject: Questions about Tricircle L2 and L3 implementation Hello Chaoyi Huang, I have read Tricirle wiki documentation and some presentations. May I ask you I have few questions about Tricircle implementation ? Here there are : 1°) L2 VxLAN How are choosen VNI identifiers ? How are choosen RT parameters ? Is a control plane used or all is configured within a pool ? 2°) L3 Does Tricircle support L3 interconnection ? Have you documentation about that ?
