虚拟机使用VXLAN 通过EVPN打通VXLAN隧道，需求是用户能够访问虚拟机

VXLAN EVPN 普通用户访问虚拟机

 

 

基本拓扑是使用OSPF打通  PC6-9是虚拟机 地址是192.168.10.1  20.1   10.2   20.2

现在可以跨网段互访

需求是用户可以访问虚拟机

# leaf设备

 

# 根据用户侧以太网服务实例的报文匹配规则创建IPL上的AC时，

# 用户侧以太网服务实例配置的报文匹配规则只能为匹配报文的外层VLAN tag（encapsulation s-vid vlan-id）、

# 匹配不携带VLAN tag的所有报文（encapsulation untagged），且AC的接入模式必须为VLAN模式。

# 采用VXLAN ID映射方式生成IPL上动态AC的报文匹配规则，AC的接入模式必须为VLAN模式。

# 配置L3   vni

# 这里UP主觉得多此一举 华为的直接在ipv4地址族下配置的

# 这里  1111 无所谓俩台leaf相同即可

#

interface Vsi-interface8191

这里配置完成后可以跨网段互访了，但是需要把EVPN的地址引入到基础路由然后使普通用户可以访问
