Hello, Julien, Both should works, you can make one VNF being deployed into two OpenStack instances, or make two VNFs work in load-balancing mode.
Currently Tricircle support associating one VIP in two OpenStack instances (through allowed address pair), it's up to VNFs how to make use of the enabling networking capabilities by Tricircle.

According to the content "show how a VNF can run in 2 OpenStack instances" and the link https://git.opnfv.org/multisite/tree/docs/requirements/VNF_high_availability_across_VIM.rst. I'm not sure that it is one VNF or two VNFs(active VNF + standby VNF) in the Demo. If it is one VNF, is it possible: 1. Some VMs in active mode are in openstack1, and other VMs in active mode are in openstack2; 2. Can VMs working in load balance mode across openstack1 and openstack2? BR, Julien joehuang <joehu...@huawei.com<mailto:joehu...@huawei.com>>于2017年3月16日周四 上午10:44写道： Hello, In multisite, we have one use cases ever discussed: a VNF (telecom application) should, be able to realize high availability deployment across OpenStack instances. For more detail of such an use cases, you can refer to https://git.opnfv.org/multisite/tree/docs/requirements/VNF_high_availability_across_VIM.rst Now, it's time to bring it into reality. After Tricircle provides cross OpenStack L2/L3 networking automation capability based on VxLAN, we'd like to have a demo in OPNFV Beijing summit to show how a VNF can run in 2 OpenStack instances and achieve high availability regardless how much nine, planned or unplanned downtime of an OpenStack cloud would be. The VNF will work in cluster, active/active or active/standby mode, and it was deployed into two OpenStack instances, overlay VxLAN network will provide network plane for session/or other data replication between VNF parts, and also provide the VIP for VNF to provide service, if the VNF is running in active/standby, the standby VNF can take over the VIP and continue to provide service after the master or the openstack cloud is failed. If you are interested in such an use case, please join us, help would be appreciated: 1. Provide or integrate sample VNF which is able to be deployed into multiple OpenStack instances to reach cloud level redundancy/failure escape. 2. Joint demo in Beijing OPNFV summit. 3. Build multi-site general infrastructure in E-release for CI/Functest/3rd party service, to provide general multi-region environment for services like Tricircle/Kingbird/Domino/Tacker which deal with multi-region functionalities.
