組網需求
企業在不同的資料中心中都擁有自己的VM，伺服器1上的VM1屬於VLAN 30，伺服器2上的VM1屬於VLAN 20，伺服器1和伺服器2位於相同網段。現需要配置透過VXLAN實現相同網段使用者通訊。
透過配置VXLAN實現相同網段使用者通訊組網圖配置思路
採用如下思路配置透過VXLAN實現相同網段使用者通訊：
分別配置路由協議，保證網路三層互通。分別配置業務接入點實現區分業務流量。使用EVPN作VXLAN控制平面功能。配置BGP EVPN對等體關係。配置EVPN例項。配置頭端複製功能。資料準備
為完成此配置例，需準備如下的資料：
VM所屬的VLAN ID分別是VLAN 20和VLAN 30。網路中裝置互連的介面IP地址。網路中使用的IGP（Internal Gateway Protocol）路由型別是OSPF（Open Shortest Path First）。廣播域BD 20，30VXLAN網路標識VNI 5020。EVPN例項的RD值為1111：1111，RT值為1111：1111。RD值為2222：2222，RT值為2222：2222。操作步驟Spine1配置sysname spine1
