Which of the following statements is false about centralized gateway deployment using BGP EVPN?

Centralized gateway deployment using BGP EVPN in Huawei’s data center networks (e.g., CloudFabric) involves a gateway handling Layer 3 routing for VXLAN overlays. Let’s evaluate each statement:

A. When configuring a VTEP, you need to create a Layer 2 BD and bind a VNI to the Layer 2 BD:A Bridge Domain (BD) is a Layer 2 broadcast domain in VXLAN, and a Virtual Network Identifier (VNI) is bound to it to segment traffic. This is a standard step when configuring a VXLAN Tunnel Endpoint (VTEP) to map the overlay network.TRUE.

B. A VXLAN tunnel is identified by a pair of VTEP IP addresses and can be established if the local and remote VTEP IP addresses are reachable to each other at Layer 3:VXLAN tunnels are established between VTEPs using their IP addresses as endpoints. Layer 3 reachability (e.g., via underlay routing) is required for tunnel establishment.TRUE.

C. When BGP EVPN is used to dynamically establish a VXLAN tunnel, the local and remote VTEPs first establish a BGP EVPN peer relationship and then exchange BGP EVPN routes to transmit VNI and VTEP IP address information. A VXLAN tunnel is then dynamically established between them:In BGP EVPN, VTEPs establish a BGP peer relationship, exchange routes (e.g., Type 2 for MAC/IP or Type 3 for multicast), and share VNI and VTEP IP details, enabling dynamic tunnel setup.TRUE.

D. When configuring a VTEP, you need to create an EVPN Instance in the Layer 2 BDand configure an RD for the local EVPN instance. You do not need to configure an RT:An EVPN Instance (EVI) is created within a BD, and a Route Distinguisher (RD) is configured to make routes unique. However, Route Targets (RTs) are also required to control route import/export between EVPN peers, ensuring proper VNI and route distribution. Stating that RT configuration is not needed is incorrect, as RTs are essential for BGP EVPN operation.FALSE.

Thus,Dis the false statement because RT configuration is necessary in centralized gateway deployment with BGP EVPN.References:Huawei CloudFabric Data Center Network Solution – BGP EVPN Configuration; HCIP-Data Center Network Training – EVPN Gateway Deployment.
