OpenContrail cluster overview¶

OpenContrail provides the following types of networking to an OpenStack environment running on MCP cluster:

• Basic networking that includes IP address management, security groups, floating IP addresses, and so on
• Advanced networking that includes DPDK network virtualization and SR-IOV

OpenContrail is based on the overlay networking, where all containers are connected to a virtual network with encapsulation (MPLSoGRE, MPLSoUDP, VXLAN).

In the current network model, the OpenContrail vRouter uses different gateways for the control and data planes.
