02-VXLAN组网环境下使用GIR实现零丢包软件升级典型配置举例


1  简介

本文档介绍VXLAN支持M-LAG组网环境下使用GIR实现零丢包软件升级典型配置举例。

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VXLAN和GIR特性。

3  使用限制

3.1  S12500GAF系列交换机使用限制

仅SF系列接口板支持VXLAN功能。

4  VXLAN支持M-LAG组网环境下使用GIR实现零丢包软件升级典型配置举例

4.1  组网需求

图1所示:

·     Device A、Device B为与Device E连接的分布式VXLAN IP网关,Device A、Device B跨设备链路聚合为一台虚拟VXLAN IP网关,采用直连模式peer-link链路。Device E属于VXLAN 10。

·     Device C、Device D为与Device F连接的分布式VXLAN IP网关,Device C、Device D跨设备链路聚合为一台虚拟VXLAN IP网关,采用直连模式peer-link链路。Device F属于VXLAN 20。

·     配置Device B进入维护模式,流量切换到Device A,等Device B完成升级后再将流量从Device A切换到Device B,再升级Device A。

·     配置Device D进入维护模式,流量切换到Device C,等Device D完成升级后再将流量从Device C切换到Device D,再升级Device C。

4.3  配置思路

采用如下思路进行配置:

·     Device A、Device B与Device C、Device D分别组成两个M-LAG系统。

·     配置Device A、Device B、Device C和Device D为VTEP设备,配置Device E为核心设备。

·     先使用GIR隔离并升级从设备Device B,然后再使用GIR隔离并升级主设备Device A。

·     先使用GIR隔离并升级从设备Device D,然后再使用GIR隔离并升级主设备Device C。

4.4  配置注意事项

以太网服务实例所在的端口需要允许该以太网服务实例匹配的VLAN通过。

使用GIR完成M-LAG组网下的设备升级或替换时,需要注意如下事项:

·     不建议针对路由和聚合业务分别配置隔离功能,避免因遗漏配置导致丢包等问题。

·     指定下次启动使用的配置文件时,配置文件中需要包含维护模式的配置。

4.5  配置步骤

(1)     配置IP地址和单播路由协议

# 配置各接口的IP地址和子网掩码。(具体配置过程略)

# 在IP核心网络内配置路由协议,发布各接口IP地址(包括Loopback接口的IP地址)对应网段的路由,确保设备之间路由可达。(具体配置过程略)

(5)     流量回切完成后,验证业务是否正常

检查业务是否正常的两种方法:

·     将收集的各种表项(如路由表、FIB表、MAC地址表等)与升级之前的表项进行对比,检查是否有丢失;对比升级前后的业务流量是否一致。

·     与运维人员一起查看当前业务是否正常,服务器等能否正常运行。

(6)     检查设备是否处于普通模式

(7)     保存配置,从设备升级完成

2. 升级主设备(Device A)

升级Device A的步骤与“1. 升级从设备(Device B)”的步骤一致,这里不再赘述。

3. 升级从设备(Device D)

升级Device D的步骤与“1. 升级从设备(Device B)”的步骤一致,这里不再赘述。

4. 升级主设备(Device C)

升级Device C的步骤与“1. 升级从设备(Device B)”的步骤一致,这里不再赘述。

5. 替换M-LAG故障设备

如果用户对业务收敛时间要求较高,且故障设备可以切换到维护模式,也可以在维护模式下替换设备,请按如下步骤替换:

(1)     故障设备执行gir system-mode maintenance命令从普通模式切换到维护模式,并保存配置。

(2)     将故障设备的配置文件导入到新设备上。

(3)     在新设备上指定版本文件和配置文件,重启新设备,使指定版本文件和配置文件生效。

(4)     将新设备下电或关闭所有物理端口。

(5)     关闭故障设备所有物理端口或故障设备下电(待替换设备较多时建议采用下电的方式)。

(6)     替换故障设备。

(7)     为新设备连接线缆。

(8)     新设备上电或开启所有物理端口。

(9)     新设备执行undo gir system-mode maintenance命令从维护模式切回普通模式并保存配置。

(2)     验证主机之间可以互访

虚拟机Device E和Device F之间可以互访。Device E与Device A或Device B相连的链路断开后,Device E和Device F之间仍然可以通过另一台设备互访。

(3)     验证升级丢包情况

在升级Device A过程中监控Device G与Device E直接流量的丢包情况,经验值Device G与Device E之间无丢包情况发生。
