different virtual-network IP addresses.
Example: VXLAN BGP EVPN — Centralized L3 gateway
The following VXLAN with BGP EVPN example uses a centralized Layer 3 gateway to perform virtual-network routing. It is
based on the sample configuration in Example: VXLAN BGP EVPN — Multiple AS topology.
In the VXLAN BGP EVPN multiple AS topology, all VTEPs are configured to perform distributed L3 gateway routing, in which
each VTEP routes VXLAN traffic. Routing decisions are made by ingress VTEPs.
However, in a multi-tenant network, some VTEPs may operate only in Layer 2 VXLAN mode and perform only Layer 2 functions.
In this case, configure routing for Layer 2 VTEPs on one Layer 3 VTEP that supports Layer 3 VXLAN functionality. The Layer 2
VXLAN-capable VTEPs are connected with the centralized Layer 3 gateway either directly or through an IP underlay fabric. Any
ingress routing traffic on a Layer 2 VTEP is switched to the Layer 3 centralized gateway. All routing decisions are made by the
centralized gateway to forward VXLAN traffic to the destination Layer 2 VTEP.
The following centralized L3 gateway example for VXLAN BGP EVPN uses a Clos leaf-spine topology. In this example:
● VTEP 1 and VTEP 2 in VLT 1 operate as a L2 gateway.
● VTEP 3 and VTEP 4 in VLT 2 operate as a centralized L3 gateway.
● Host A and Host B are connected to the L2 gateway. The L2 gateway is connected to a centralized L3 gateway through an
IP underlay fabric.
● You must configure the IP address and anycast IP address of the virtual networks in the centralized L3 gateway VTEP. It is
not necessary to configure these addresses in the L2 gateway VTEPs.
Routing for tenant L3 traffic is not performed on the L2 VTEPs. The L2 VTEPs forward tenant traffic to the centralized L3
gateway in VLT 2. The L3 gateway routes traffic between L2 tenant segments.
