H3C EVPN 网关配置

一、H3C集中式EVPN网关配置

1、需求：

使用Router A、Router B为与服务器连接的VTEP设备；

Router C为与广域网连接的集中式EVPN网关设备；

Router D为RR，负责在路由器之间反射BGP路由。

虚拟机VM 1和VM 3属于VXLAN 10；VM 2和VM 4属于VXLAN 20。

相同VXLAN之间可以二层互通，不同VXLAN之间、VXLAN与广域网之间可以通过集中式EVPN网关互通。

2、实验步骤：

1、配置IP地址和单播路由协议

2、配置VXLAN与VSI，创建EVPN实例

3、配置BGP L2VPN EVPN

4、接口关联VSI实例

3、拓扑架构：

4、配置命令：

Device-RTD:

#

sysname RTD

#

ip vpn-instance vpn1     //创建VPN实例

route-distinguisher 1:1  //赋予RD值，RD是本地PE路由器上VPN的唯一标识

#

address-family ipv4     //创建RIB IPv4地址族，并进入RIB IPv4地址族视图

vpn-target 2:2 import-extcommunity    //配置入方向的RT值

vpn-target 2:2 export-extcommunity  //配置出方向的RT值

#

address-family evpn   //进入IPV4 EVPN视图

vpn-target 1:1 import-extcommunity  //配置入方向的RT值

vpn-target 1:1 export-extcommunity  //配置出方向的RT值

#

vxlan tunnel mac-learning disable   //命令用来关闭远端MAC地址自动学习功能，如果网络中存在攻击，为了避免学习到错误的远端MAC地址，可以通过本命令手工关闭远端MAC地址自动学习功能。

#

ospf 1    //配置OSPF路由

area 0.0.0.0

#

l2vpn enable   //全局开启l2vpn能力

vxlan tunnel arp-learning disable   //命令用来关闭远端ARP自动学习功能

#

vsi vpna    //VXLAN与VSI绑定

5、VM配置截图：

6、测试结果：

查看Router C上的EVPN路由信息，可以看到Router C发送了网关的MAC/IP路由和IMET（Inclusive multicast Ethernet tag route集成多播以太标记路由）路由，并接收到Router A和Router B发送的MAC/IP路由和IMET路由。

查看Router C上的Tunnel接口信息，可以看到VXLAN模式的Tunnel接口处于up状态。

查看Router C上的VSI虚接口信息，可以看到VSI虚接口处于up状态。

查看Router C上的VSI信息，可以看到VSI内创建的VXLAN、与VXLAN关联的VXLAN隧道、与VSI关联的VSI虚接口等信息。

查看Router C上VSI的EVPN ARP表项信息，可以看到已学习到了虚拟机的ARP信息。

查看Router C上FIB表项信息，可以看到已学习到了虚拟机的转发表项信息。

虚拟机VM 1、VM 2、VM 3、VM 4之间互访测试。

二、H3C 分布式EVPN网关配置

1、拓扑说明：

Router A、Router B为分布式EVPN网关设备；

Router C为与外部网络（广域网）连接的边界网关设备；

Router D为RR（反射器），负责在路由器之间反射BGP路由；

虚拟机VM 1和VM 3属于VXLAN 10；

VM 2和VM 4属于VXLAN 20；

相同VXLAN之间可以二层互通；

不同VXLAN之间通过分布式EVPN网关实现三层互通；

VXLAN与广域网之间通过边界网关实现三层互通。
