Contiv comes straight out of Cisco's labs, an open-source container networking solution designed for heterogeneous container deployments across virtual machines, bare metals, and both public and private clouds. It also integrates seamlessly with mainstream container orchestration systems. Contiv's primary strength lies in offering multi-tenant networks with support for various networking modes such as L2 (VLAN), L3 (BGP), Overlay (VXLAN), and Cisco's proprietary ACI.
Note: The Contiv project is no longer actively maintained. Users are advised to switch to other, more active projects.
Key Features:
Native support for Tenants, with each Tenant being a virtual routing and forwarding (VRF)
Two network modes:
L2 VLAN Bridged
Routed network, e.g., vxlan, BGP, ACI
Network Policy features, including Bandwidth and Isolation

Contiv: A Glimpse into Cisco's Container Networking Mastery
Contiv is a brainchild of Cisco, designed as a resourceful and open-source networking framework for containers. This flexible solution cuts across various platforms from virtual machines and bare metal servers to both flavors of clouds—public and private. It's crafted to work effortlessly with popular container orchestration tools, boasting an edge with its direct multi-tenant network offerings and compatibility with L2 (VLAN), L3 (BGP), Overlay (VXLAN), not to forget Cisco's own ACI technology.
Heads-up: Contiv is no longer on the active roster for updates. Users might want to explore other solutions on the move.
Essential Highlights:
Native multi-tenant support—think of it as each Tenant owning a personalized VRF
Dual network modes to choose from:
L2 VLAN Bridged mode
The routed network affair, with flavors like vxlan, BGP, and ACI
Network policies that cater to setting Bandwidth caps and ensuring Isolation
