What is ML2 OpenStack?

The Modular Layer 2 (ML2) neutron plug-in is a framework allowing OpenStack Networking to simultaneously use the variety of layer 2 networking technologies found in complex real-world data centers. The ML2 framework distinguishes between the two kinds of drivers that can be configured: Type drivers.

What are L2 agents?

Very generally speaking, the L2 agent is primarily responsible for ensuring that new instances can communicate within the same project/tenant, and enforcing security group rules.

What is the purpose of neutron in OpenStack?

Neutron is an OpenStack project to provide “network connectivity as a service” between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova). It implements the Neutron API. This documentation is generated by the Sphinx toolkit and lives in the source tree.

What provides networking capability for OpenStack?

Neutron is an OpenStack project to provide “networking as a service” between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).

How do I find my openstack tenant ID?

A “tenant” (or “project”) has a name and an ID. Your “myTenant” is a project name. The tenant ID or project ID is a long unique identifier. You can lookup the ID for a project using the openstack command; e.g. openstack project show myTenant .

Which project is dedicated on networking in OpenStack?

The project code-name for Networking services is neutron. OpenStack Networking handles the creation and management of a virtual networking infrastructure, including networks, switches, subnets, and routers for devices managed by the OpenStack Compute service (nova).

Is neutron a SDN?

OpenStack Neutron is an SDN networking project focused on delivering networking-as-a-service (NaaS) in virtual compute environments. Neutron has replaced the original networking application program interface (API), called Quantum, in OpenStack.

What is the neutron API in OpenStack?

Neutron is an OpenStack project to provide “network connectivity as a service” between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova). It implements the OpenStack Networking API. This documentation is generated by the Sphinx toolkit and lives in the source tree.

What are the key components of OpenStack?

OpenStack Components

  • Compute (Nova)
  • Image Service (Glance)
  • Object Storage (Swift)
  • Dashboard (Horizon)
  • Identity Service (Keystone)
  • Networking (Neutron)
  • Block Storage (Cinder)
  • Telemetry (Ceilometer)

What is the difference between VLAN and Vxlan?

The main difference is that VLAN uses the tag on the layer 2 frame for encapsulation and can scale up to 4000 VLANs. VXLAN, on the other hand, encapsulates the MAC in UDP and is capable of scaling up to 16 million VxLAN segments.

What is and tenant in OpenStack?

A tenant describes a project with an assigned number of OpenStack users and resources. It is possible to set up quotas for each tenant. This enables multiple projects to use a single cloud without interfering with each other’s permissions and resources. The words project and tenant are used interchangeably.

What are the 3 main components of OpenStack?

Introducing OpenStack and its components for cloud computing

  • Cloud Software as a Service (SaaS),
  • Cloud Platform as a Service (PaaS),
  • Cloud Infrastructure as a Service (IaaS))
