1  简介

本文档介绍EVPN(Ethernet Virtual Private Network,以太网虚拟专用网络)和DRNI(Distributed Resilient Network Interconnect,分布式弹性网络互连)结合使用的典型配置举例。

·     EVPN是一种二层VPN技术,控制平面采用MP-BGP通告EVPN路由信息,数据平面采用VXLAN封装方式转发报文。

·     DRNI是一种跨设备链路聚合技术,将两台物理设备在聚合层面虚拟成一台设备来实现跨设备链路聚合,从而提供设备级冗余保护和流量负载分担。

通过EVPN和DRNI结合部署的方式,将两台物理设备连接起来虚拟成一台设备,使用该虚拟设备作为VTEP(既可以是仅用于二层转发的VTEP,也可以是EVPN网关),可以避免VTEP单点故障对网络造成影响,从而提高EVPN网络的可靠性。

2  配置前提

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EVPN和DRNI特性。

3  使用限制

在二层转发组网中,以太网服务实例的报文匹配规则和接入模式之间存在如下限制:

·     报文匹配规则为匹配带VLAN Tag的报文(encapsulation tagged)、匹配不带VLAN Tag的报文(encapsulation untagged)、缺省报文匹配规则(encapsulation default)时,AC的接入模式必须配置为Ethernet接入模式,否则设备向VM发送报文时无法判断为报文添加的VLAN tag。

·     其他情况下,AC的接入模式既可以配置为Ethernet接入模式,也可以配置为VLAN接入模式。

EVPN网关在对报文进行三层转发时,以太网服务实例的报文匹配规则和接入模式只能配置为:

·     匹配不带VLAN Tag的报文(encapsulation untagged),且必须使用Ethernet接入模式。

·     仅匹配外层VLAN Tag(encapsulation s-vid { vlan-id [ only-tagged ] | vlan-id-list }),且必须使用VLAN接入模式。

4  EVPN和DRNI二层转发配置举例(以太网聚合链路作为IPL)

4.1  组网需求

Switch A、Switch B、Switch D为与服务器连接的VTEP设备。Switch A和Switch B通过DRNI虚拟为一台VTEP设备,Switch A和Switch B之间通过IPL(Intra-Portal Link,内部控制链路)同步MAC地址和ARP信息,以确保两台VTEP上的MAC地址和ARP信息保持一致。Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由。本组网采用以太网聚合链路作为IPL。

Switch A和Switch B均通过以太网链路与下行的虚拟机VM 1、VM 2连接,要求在连接每一台虚拟机的链路间跨设备建立二层聚合接口,避免单条以太网链路故障导致虚拟机无法访问网络。

虚拟机VM 1、VM 2和VM 3同属于VXLAN 10,通过EVPN实现不同站点间的二层互通。

图1 EVPNDRNI二层转发组网图(以太网聚合链路作为IPL)

 

4.2  配置思路

·     在交换机上配置路由协议,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上开启EVPN支持分布式聚合功能,使两台设备虚拟为一台VTEP设备。

·     配置Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由

·     在Switch A、Switch B和Switch D上配置EVPN,使VTEP之间通过BGP EVPN路由实现自动发现邻居、自动建立/关联VXLAN隧道、通告MAC/IP的可达性等,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、Switch B和Switch D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。

4.3  使用版本

本举例是在S6860-CMW710-R2612版本上进行配置和验证的。

4.4  配置注意事项

·     分布式聚合的两台VTEP上EVPN配置必须一致。

·     匹配相同外层VLAN Tag(S-VID)的不同以太网服务实例必须关联相同的VSI。

·     IPP口与IRF物理端口都需要配置undo mac-address static source-check enable命令。

·     建议使用Loopback接口的IP地址作为分布式聚合的虚拟VTEP地址。

5  EVPN和DRNI二层转发配置举例(VXLAN隧道作为IPL)

5.1  组网需求

Switch A、Switch B、Switch D为与服务器连接的VTEP设备。Switch A和Switch B通过DRNI虚拟为一台VTEP设备,Switch A和Switch B之间采用VXLAN隧道作为IPL,同步MAC地址和ARP信息,以确保两台VTEP上的MAC地址和ARP信息保持一致。Switch C同时作为路由反射器在Switch A、Switch B、Switch D之间反射路由。

Switch A和Switch B均通过以太网链路与下行的虚拟机VM 1、VM 2连接,要求在连接每一台虚拟机的链路间跨设备建立二层聚合接口,避免单条以太网链路故障导致虚拟机无法访问网络。

虚拟机VM 1、VM 2和VM 3同属于VXLAN 10,通过EVPN实现不同站点间的二层互通。

图2 EVPNDRNI二层转发组网图(VXLAN隧道作为IPL)

 

5.2  配置思路

·     在交换机上配置路由协议,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上开启EVPN支持分布式聚合模式,使两台设备虚拟为一台VTEP设备。

·     Switch A、Switch B之间通过手工方式创建VXLAN隧道作为IPL,在Switch A和Switch B之间同步MAC地址和ARP信息。

·     配置Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由

·     在Switch A、Switch B和Switch D上配置EVPN,使VTEP之间通过BGP EVPN路由实现自动发现邻居、自动建立/关联VXLAN隧道、通告MAC/IP的可达性等,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、Switch B和Switch D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。

5.3  使用版本

本举例是在S6860-CMW710-R2612版本上进行配置和验证的。

5.4  配置注意事项

·     分布式聚合的两台VTEP上EVPN配置必须一致。

·     建议使用Loopback接口的IP地址作为分布式聚合的虚拟VTEP地址。

·     DR口上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 | vlan-id-list })、匹配不携带VLAN tag的所有报文(encapsulation untagged)。

·     建议不要在分布式聚合的两台VTEP上引入外部路由。

·     在作为IPL的VXLAN隧道对应的二层以太网接口上关闭STP功能,以免上行设备错误地阻塞连接DR device的接口。

5.5  配置步骤

6  EVPN和DRNI三层转发配置举例(以太网聚合链路作为IPL)

6.1  组网需求

Switch A、Switch B、Switch D为与服务器连接的分布式EVPN网关,Switch A和Switch B通过DRNI虚拟为一台VTEP设备,Switch A和Switch B之间通过IPL同步MAC地址和ARP信息,以确保两台VTEP上的MAC地址和ARP信息保持一致。Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由。本组网采用以太网聚合链路作为IPL。

Switch A和Switch B均通过以太网链路与下行的虚拟机VM 1、VM 2、VM 3和VM 4连接,要求在连接每一台虚拟机的链路间跨设备建立二层聚合接口,避免单条以太网链路故障导致虚拟机无法访问网络。

虚拟机VM 1、VM 3和VM 5属于VXLAN 10,VM 2和VM 4属于VXLAN 20,通过分布式EVPN网关实现不同VXLAN之间互通。

图3 EVPNDRNI三层转发组网图(以太网聚合链路作为IPL)

 

6.2  配置思路

·     在交换机上配置路由协议,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上开启EVPN支持分布式聚合功能,使两台设备虚拟为一台VTEP设备。

·     配置Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由。

·     在Switch A、Switch B和Switch D上配置分布式EVPN网关,使VTEP之间通过BGP EVPN路由实现自动发现邻居、自动建立/关联VXLAN隧道、通告MAC/IP的可达性等,以便将虚拟机之间实现三层互通。

·     在Switch A、Switch B和Switch D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。

6.3  使用版本

本举例是在S6860-CMW710-R2612版本上进行配置和验证的。

6.4  配置注意事项

·     分布式聚合的两台VTEP上EVPN配置必须一致。

·     匹配相同外层VLAN Tag(S-VID)的不同以太网服务实例必须关联相同的VSI。

·     IPP口与IRF物理端口都需要配置undo mac-address static source-check enable命令。

·     建议使用Loopback接口的IP地址作为分布式聚合的虚拟VTEP地址。

6.5  配置步骤

6.5.1  配置各接口的IP地址

# 在Switch A上配置各接口的IP地址。

7  EVPN和DRNI三层转发配置举例(VXLAN隧道作为IPL)

7.1  组网需求

Switch A、Switch B、Switch D为与服务器连接的分布式EVPN网关,Switch A和Switch B通过DRNI分布式聚合为一台虚拟VTEP设备,Switch A和Switch B之间采用VXLAN隧道作为IPL;Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由。

Switch A和Switch B均通过以太网链路与下行的虚拟机VM 1、VM 2、VM 3和VM 4连接,要求在连接每一台虚拟机的链路间跨设备建立二层聚合接口,避免单条以太网链路故障导致虚拟机无法访问网络。

虚拟机VM 1、VM 3和VM 5属于VXLAN 10,VM 2和VM 4属于VXLAN 20,通过分布式EVPN网关实现不同VXLAN之间互通。

图4 EVPNDRNI三层转发组网图(VXLAN隧道作为IPL)

 

 

7.2  配置思路

·     在交换机上配置路由协议,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。

·     指定各虚拟机的网关地址。

·     在Switch A、Switch B上开启EVPN支持分布式聚合功能,使两台设备虚拟为一台VTEP设备。

·     Switch A、Switch B之间通过手工方式创建VXLAN隧道作为IPL,在Switch A和Switch B之间同步MAC地址和ARP信息。

·     配置Switch C作为路由反射器在Switch A、Switch B、Switch D之间反射路由

·     在Switch A、Switch B和Switch D上配置分布式EVPN网关,使VTEP之间通过BGP EVPN路由实现自动发现邻居、自动建立/关联VXLAN隧道、通告MAC/IP的可达性等,以便将虚拟机之间实现三层互通。

·     在Switch A、Switch B和Switch D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。

7.3  使用版本

本举例是在S6860-CMW710-R2612版本上进行配置和验证的。

7.4  配置注意事项

·     分布式聚合的两台VTEP上EVPN配置必须一致。

·     建议使用Loopback接口的IP地址作为分布式聚合的虚拟VTEP地址。

·     DR口上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 | vlan-id-list })、匹配不携带VLAN tag的所有报文(encapsulation untagged)。

·     建议不要在分布式聚合的两台VTEP上引入外部路由。

7.5  配置步骤
