本文档介绍VXLAN（Virtual eXtensible LAN，可扩展虚拟局域网络）的典型配置案例。VXLAN是基于IP网络、采用“MAC in UDP”封装形式的二层VPN技术。VXLAN可以基于已有的服务提供商或企业IP网络，为分散的物理站点提供二层互联，并能够为不同的租户提供业务隔离。VXLAN主要应用于数据中心网络。
本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请以设备实际情况为准。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解VXLAN特性。
Switch A、Switch B、Switch C为与服务器连接的VTEP设备。虚拟机VM 1、VM 2和VM 3同属于VXLAN 10。通过VXLAN实现不同站点间的二层互联，确保虚拟机在站点之间进行迁移时用户的访问流量不会中断。
图1 VXLAN二层转发配置举例
· 在IP核心网络上配置路由协议，使得各交换机的接口IP地址（包括Loopback接口IP地址）之间路由可达。本举例以OSPF路由协议为例。
· 在Switch A、Switch B和Switch C之间建立VXLAN隧道，并将VXLAN隧道与VXLAN关联，以便将虚拟机发送的二层报文封装为IP报文后在IP核心网络上转发。
· 在Switch A和Switch B的下行端口上配置以太网服务实例和相应的匹配规则，用来识别用户网络中的报文所属的VXLAN。
# 配置Switch A的接口IP地址。

如图2所示，虚拟机VM 1、VM 3属于VXLAN 10，VM 2和VM 4属于VXLAN 20。Switch A、Switch B为与服务器连接的VTEP设备，Switch C为与广域网连接的集中式VXLAN IP网关设备。通过VXLAN实现不同站点间的二层互联，并通过集中式VXLAN IP网关实现不同VXLAN之间、VXLAN与广域网之间的三层互联。

· 在IP核心网络上配置路由协议，使得各交换机的接口IP地址（包括Loopback接口IP地址）之间路由可达。本举例以OSPF路由协议为例。
· 在Switch A、Switch B和Switch C之间建立VXLAN隧道，并将VXLAN隧道与VXLAN关联，以便将虚拟机发送的二层报文封装为IP报文后在IP核心网络上转发。
· 在Switch A和Switch B的下行端口上配置以太网服务实例和相应的匹配规则，用来识别用户网络中的报文所属的VXLAN。
· 在集中式VXLAN IP网关Switch C上为每个VXLAN分别创建一个VSI虚接口，为其配置IP地址，该地址作为各自VXLAN内虚拟机的网关地址；在Switch C上配置路由协议将VSI虚接口、Vlan-interface100所在网段路由发布到L3 network，以便L3 network内的节点具有到达虚拟机的路由，本举例以OSPF路由协议为例。

Switch A、Switch B为与服务器连接的VTEP设备，Switch C和Switch D为与广域网连接的集中式VXLAN IP网关设备。虚拟机VM 1、VM 3属于VXLAN 10，虚拟机VM 2、VM 4属于VXLAN 20。通过VXLAN IP网关保护组实现Switch C和Switch D能够同时对虚拟机的跨网络报文进行三层转发，同时实现网关设备的备份。
图3 集中式VXLAN IP网关保护组配置组网图
· 在IP核心网络上配置路由协议，使得各交换机的接口IP地址（包括Loopback接口IP地址）之间路由可达。本举例以OSPF路由协议为例。
· 在Switch A、Switch B、Switch C和Switch D之间建立VXLAN隧道，并将VXLAN隧道与VXLAN关联，以便将虚拟机发送的二层报文封装为IP报文后在IP核心网络上转发。
· 在Switch A和Switch B的下行端口上配置以太网服务实例和相应的匹配规则，用来识别用户网络中的报文所属的VXLAN。
· 在集中式VXLAN IP网关Switch C和Switch D上为每个VXLAN分别创建一个VSI虚接口，并为其配置IP地址，该地址作为各自VXLAN内虚拟机的网关地址；在Switch C和Switch D上配置路由协议将VSI虚接口、Vlan-interface100所在网段路由发布到L3 network，以便L3 network内的节点具有到达虚拟机的路由，本举例以OSPF路由协议为例。
· 将Switch C和Switch D加入集中式VXLAN IP网关保护组，实现网关设备的备份。
