VXLAN as NVO solution
Network virtualization overlay (NVO) is a solution that addresses the requirements of a multi-tenant data center, especially one with virtualized hosts. An NVO network is an overlay network that is used to extend L2 connectivity among VMs belonging to a tenant segment over an underlay IP network. Each tenant payload is encapsulated in an IP packet at the originating VTEP. To access the payload, the tenant payload is stripped of the encapsulation at the destination VTEP. Each tenant segment is also known as a virtual-network and is uniquely identified in OS10 using a virtual network ID (VNID).
VXLAN is a type of encapsulation
used as an NVO solution. VXLAN encapsulates a tenant payload into IP
UDP packets for transport across the IP underlay network. In OS10, each virtual network is assigned a 24-bit number that is called a VXLAN network identifier (VNI) that the VXLAN-encapsulated packet carries. The VNI uniquely identifies the tenant segment on all VTEPs. OS10 sets up ASIC tables to:
- Enables creation of a L2 bridge flooding domain across a L3 network.
- Facilitates packet forwarding between local ports and tunneling packets from the local device to a remote device.
