ensp做vxlan evpn多活网关

VXLAN（Virtual Extensible LAN）是一种网络虚拟化技术，用于在现有的物理网络上构建虚拟的二层网络。EVPN（Ethernet VPN）是一种基于BGP（Border Gateway Protocol）的控制平面协议，用于在VXLAN网络中传递MAC地址和ARP信息。多活网关（Active-Active Gateway）是指在多个设备上同时激活网关功能，以提高网络的冗余性和可用性。 在ENSP（Enterprise Network Simulation Platform）中配置VXLAN EVPN多活网关，可以按照以下步骤进行： ### 步骤一：配置基础网络 1. **创建VLAN** ``` [Huawei] vlan batch 10 20 ``` 2. **配置接口** ``` [Huawei] interface GigabitEthernet0/0/1 [Huawei-GigabitEthernet0/0/1] port link-type trunk [Huawei-GigabitEthernet0/0/1] port trunk allow-pass vlan 10 20 [Huawei-GigabitEthernet0/0/1] quit [Huawei] interface GigabitEthernet0/0/2 [Huawei-GigabitEthernet0/0/2] port link-type access [Huawei-GigabitEthernet0/0/2] port default vlan 10 [Huawei-GigabitEthernet0/0/2] quit [Huawei] interface GigabitEthernet0/0/3 [Huawei-GigabitEthernet0/0/3] port link-type access [Huawei-GigabitEthernet0/0/3] port default vlan 20 [Huawei-GigabitEthernet0/0/3] quit ``` ### 步骤二：配置VXLAN 1. **创建NVE接口** ``` [Huawei] interface Nve1 [Huawei-Nve1] source 1.1.1.1 [Huawei-Nve1] vni 5010 head-end peer-list 2.2.2.2 [Huawei-Nve1] vni 5020 head-end peer-list 2.2.2.2 [Huawei-Nve1] quit ``` 2. **配置VXLAN隧道** ``` [Huawei] bridge-domain 10 [Huawei-bd10] vxlan vni 5010 [Huawei-bd10] quit [Huawei] bridge-domain 20 [Huawei-bd20] vxlan vni 5020 [Huawei-bd20] quit ``` ### 步骤三：配置EVPN 1. **配置BGP** ``` [Huawei] bgp 65001 [Huawei-bgp] peer 2.2.2.2 as-number 65001 [Huawei-bgp] peer 2.2.2.2 connect-interface Loopback0 [Huawei-bgp] address-family l2vpn evpn [Huawei-bgp-af-evpn] peer 2.2.2.2 enable [Huawei-bgp-af-evpn] quit [Huawei-bgp] quit ``` 2. **配置EVPN实例** ``` [Huawei] evpn-overlay enable [Huawei] evpn-overlay vni 5010 5020 [Huawei] evpn-overlay peer 2.2.2.2 ``` ### 步骤四：验证配置 1. **查看VXLAN隧道状态** ``` [Huawei] display vxlan tunnel ``` 2. **查看EVPN路由信息** ``` [Huawei] display bgp l2vpn evpn routing-table ``` 通过以上步骤，你可以在ENSP中配置VXLAN EVPN多活网关，实现网络的冗余性和高可用性。
