This article provides information about Lenovo CNOS hardware VXLAN gateway for VMware NSX-v 6.4.1.

Lenovo Cloud Network OS (CNOS) hardware VXLAN gateway services for VMware NSX solution provides a high-performance network fabric that seamlessly connects workloads on the virtual network to devices connected to the physical network. 
Lenovo’s VXLAN gateway services integrates with VMware’s NSX solution to extend communication from the virtual overlay network to non-virtualized devices connected to external network.  This allows devices from existing physical networks like bare metal servers, database servers, and other non-virtualized systems to participate in the same network.
Performing hardware VTEP services, the encapsulation and de-capsulation of Ethernet frames to route traffic across the logical network infrastructure (independent of physical location), enables Lenovo to provide a robust and resilient L2 Gateway for VXLAN connectivity over any supported IP fabric.  Lenovo CNOS supports deployment options for both standalone and high availability gateway servers.

Additional support information

Sample problem scenarios include:
  • VXLAN gateway not available – due to VXLAN tunnel IP not configured; fix by manually configuring tunnel IP.
  • VXLAN tunnels across more than one next-hop is not working across L2 network; due to Trident2 limitation L2 underlay does not support for multiple hops.  For Trident2 platforms use a L3 routed underlay.
