4. ROH (Routing on Host/Node)

In ROH mode every server/node establishes a BGP session with each network switch, advertises it’s loopback interface IP address as it’s the main IP. Netris supports ROH mode natively and allows operation for zero-configuration on Kubernetes nodes. 

Benefits of ROH are:

  • Best network fault-tolerance 
  • Equal utilization of all physical links
  • High-performance L3 anycast load balancing
