BGP EVPN compared to static VXLAN

OS10 supports two types of VXLAN NVO overlay networks:
  • Static VXLAN
  • BGP EVPN
Configure and operate static VXLANs and BGP EVPNs for VXLAN in the same way:
  • Manually configure the overlay and underlay networks.
  • Manually configure each virtual network and VNI.
  • Manually configure access port membership in a virtual network.
  • Existing routing protocols provision and learn underlay reachability to VTEP peers.

However, static VXLANs and BGP EVPNs for VXLAN differ as described:

To start sending and receiving virtual-network traffic to and from a remote VTEP, manually configure the VTEP as a member of the virtual network. No manual configuration is required. Each remote VTEP is automatically learned as a member of a virtual network from the EVPN routes received from the remote VTEP. After a remote VTEP address is learned, VXLAN traffic is sent to, and received from, the VTEP.
Data packets learn remote hosts after decapsulation of the VXLAN header in the data plane.Remote host MAC addresses are learned in the control plane using BGP EVPN Type 2 routes and MAC/IP advertisements.
