Problem with Openstack routers and arista-ml2 driver with HPB

Hi! I have a problem with VLAN – VNI mapping for openstack routers on network nodes. My environment: Openstack Ussuri Neutron with legacy routers realisation (not DVR) Some compute nodes Two network nodes (with l3, dhcp and metadata agents) Arista-neutron-ml2-driver with VXLAN HPB Arista 7050SX integrated with CVX   Problem: I create a tenant network. Network is visible on CVX (show openstack network). Next I connect instance to this network and driver correctly mapped VNI to VLAN and dattach VLAN to compute interface on the switches. Next I enable DHCP on this network and driver correctly attach VLAN to network...

Questions about ML2 OpenStack

Hi guys, I build a testbed OpenStack with an Arista router as TOR. I tried ML2 features but it’s not clear to me in some facets. Here are my concerns and I want to know more detail about them. 1. ML2 Hierarchical Port Binding As I know this feature is used to offload encap/decap VXLAN packets at physical router TOR rather than using software (such as ovs) on compute node. However in my testbed, I only use one Arista TOR router connect to compute node A. I have another compute node B without any TOR connected to it. Does ML2...

Openstack ML2 driver does not create HA network

We’re deploying Openstack Neutron (based on Redhat Openstack Platform 10) with arista switches. In this pass we’re only using the Layer 2 driver, allowing Neutron to take care of the L3. With this configuration neutron creates a network for the routers to communicate VRRP over, we see this being created on our CVX controller, but as the network never gets any ports associated with it so CVX does not communicate this to the physical switches. This means that the neutron routers go “split brain” as they have no l2 connection between them. I’ve got a case open with support about...

OpenStack Enhancements

This release introduces enhancements to the CloudVision eXchange and OpenStack integration. The following features were added as part of this release: OpenStack Ironic Integration OpenStack Keystone v3 support OpenStack DVR support OpenStack Ironic Integration Through OpenStack Ironic integration with Neutron, it is possible to provision bare metal servers that are attached to Arista switches and connect them to tenant networks. All of the features that Arista supports for provisioning networks for VMs is extended to bare metal servers. This includes automatic VLAN-to-VNI mapping and Hierarchical Port Binding. Security groups can be applied as ACLs on switch interfaces connected to bare...
