Table 80. Differences between Static VXLAN and VXLAN BGP EVPN Static VXLAN VXLAN BGP EVPN 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 Remote host MAC addresses are learned in the control plane using header in the data plane. BGP EVPN Type 2 routes and MAC/IP advertisements. VXLAN BGP EVPN operation The EVPN address family allows VXLAN to carry EVPN routes in External Border Gateway Protocol (eBGP) and Internal Border Gateway Protocol (iBGP) sessions. In a data center network, use eBGP or iBGP for route exchange in both the IP underlay network and EVPN. The following sample BGP EVPN topology shows a leaf-spine data center network where eBGP exchanges IP routes in the IP underlay network, and exchanges EVPN routes in the VXLAN overlay network. All spine nodes are in one autonomous system-AS 65535. All leaf nodes are in another autonomous system-AS 65000. To advertise underlay IP routes, eBGP peer sessions establish between the leaf and spine nodes using an interface IP address. To advertise EVPN routes, eBGP peer sessions between the leaf and spine nodes use a Loopback IP address. Figure 13. BGP EVPN topology Leaf nodes VXLAN 889
