华为EVPN网关配置

一、华为集中式EVPN网关配置

1、拓扑

设备：SW1，SW2，SW3用CE12800设备

ACC-1，ACC-2用SW5700设备

2、需求

SW2为Border设备，SW1和SW3为Edge设备 PC1属于VLAN100，PC2属于VLAN200，Border和Edge设备配置了OSPF协议，要求PC1和PC2使用集中式VXLAN技术，实现三层互访

PC1地址：172.16.10.10 网关：172.16.10.1

PC2地址：172.16.20.10 网关：172.16.20.1

3、操作

1. 基础连通性配置

3. 业务接入点配置

SW1上完成业务接入点的配置，创建子接口与ACC-1互通，终结VLAN100，并与BD10进行绑定。

SW3上完成业务接入点的配置，创建子接口与ACC-2互通，终结VLAN200，并与BD20进行绑定。

ACC-1与PC连接的接口配置为Access接口，PVID 100，与SW1、SW3互联的接口配置为Trunk接口，放通VLAN 100。

ACC-2与PC连接的接口配置为Access接口，PVID200，与SW1、SW3互联的接口配置为Trunk接口，放通VLAN 100。

4、验证

测试

二、华为 Vxlan-BGP 分布式EVPN网关配置

VXLAN分布式网关可以解决VXLAN集中式网关的转发路径不优化，三层网关ARP或ND表项规格瓶颈问题。

本文主要通过华为ENSP模拟VXLAN-BGP EVPN分布式网关配置。

1、配置思路

配置underlay网络实现互联互通
启用VXLAN功能
配置业务接入点
启用EVPN功能
配置BGP对等体
配置EVPN实例
配置头端配置列表
配置VPN实例
配置VBDIF并绑定VPN实例，配置发布路由类型
配置BGP对等体路由类型

此次环境如下：

ensp 版本1.3.00.100

ce12800 版本V200R005C10SPC607B607

virtualbox 版本5.1.26

此次拓扑如下：

2、配置CE1-CE3实现三层互通

CE1：

复制代码

[ce1]ospf 1 router-id 1.1.1.1	\\配置OSPF进程1

[ce1-ospf-1]area 0

[ce1-ospf-1-area-0.0.0.0]quit

[ce1-ospf-1]quit

[ce1]interface  g1/0/0

[ce1-ge1/0/0]undo shutdown

[ce1-ge1/0/0]undo portswitch

[ce1-ge1/0/0]ip address 192.168.12.1 255.255.255.0

[ce1-ge1/0/0]ospf enable 1 area 0	\\端口加入OSPF进程

[ce1-ge1/0/0]interface loopback 0 

[ce1-loopback1]ip address 1.1.1.1 255.255.255.255

[ce1-loopback1]ospf enable 1 area 0

[ce1-loopback1]interface g1/0/1

[ce1-ge1/0/1]undo shutdown

[ce1-ge1/0/1]undo portswitch

[ce1-ge1/0/1]ip address 192.168.13.1 255.255.255.255

[ce1-ge1/0/1]ospf enable 1 area 0

[ce1-ge1/0/1]quit

[ce1]commit

CE2：

复制代码

[ce2]ospf 1 router-id 2.2.2.2

[ce2-ospf-1]area 0

[ce2-ospf-1-area-0.0.0.0]quit

[ce2-ospf-1]quit

[ce2]interface  g1/0/0

[ce2-ge1/0/0]undo shutdown

[ce2-ge1/0/0]undo portswitch

[ce2-ge1/0/0]ip address 192.168.12.2 255.255.255.0

[ce2-ge1/0/0]ospf enable 1 area 0

[ce2-ge1/0/0]interface loopback 0 

[ce2-loopback1]ip address 2.2.2.2 255.255.255.255

[ce2-loopback1]ospf enable 1 area 0

[ce2-loopback1]quit

[ce2]commit

CE3：

复制代码

[ce3]ospf 1 router-id 3.3.3.3

[ce3-ospf-1]area 0

[ce3-ospf-1-area-0.0.0.0]quit

[ce3-ospf-1]quit

[ce3]interface  g1/0/0

[ce3-ge1/0/0]undo shutdown

[ce3-ge1/0/0]undo portswitch

[ce3-ge1/0/0]ip address 192.168.13.3 255.255.255.0

[ce3-ge1/0/0]ospf enable 1 area 0

[ce3-ge1/0/0]interface loopback 0

[ce3-loopback1]ip address 3.3.3.3 255.255.255.255

[ce3-loopback1]ospf enable 1 area 0

[ce3-loopback1]quit

[ce3]commit

配置注意点：

1）注意交换机端口默认状态为shutdown，需要手动undo shutdown

ce3上ospf状态查看

3、配置VXLAN隧道

复制代码

ip tunnel mode vxlan	\\配置隧道模式为vxlan

assign forward nvo3 acl extend enable	\\使能vxlan的ACL扩展功能，以防ACL叠加失败

配置注意点：

此处模拟器不支持配置命令，实际环境还是要配置的，配置命令后交换机需要重启。

4、配置LSW1 LSW2

lsw1:

复制代码

[lsw1]vlan 10

[lsw1-vlan10]quit

[lsw1]vlan 20

[lsw1-vlan20]quit
