H3C-SR8800 虚拟化配置

1 简介

本文档介绍了配置两台成员设备的IRF的配置举例。

IRF（Intelligent Resilient Framework，智能弹性架构）是H3C自主研发的软件虚拟化技术，它的核心思想是将多台设备通过物理IRF端口连接在一起，进行必要的配置后，虚拟化成一台“虚拟设备”，通过该“虚拟设备”来实现多台设备的协同工作、统一管理和不间断维护。

为了便于描述，本文把这个虚拟化形成的设备称为IRF。

2 配置前提

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。

请确保成员设备间的IRF物理连线正确连接，与配置组网图保持一致。

本文假设您已了解IRF特性。

3 使用限制

1. IRF形成条件

在配置IRF前，SR8800-X必须满足以下条件，否则不能形成IRF：

?

?

?

? SR8800-X路由器只支持与其他SR8800-X路由器之间建立IRF，且IRF中的成员设备最多为2台。 建立IRF前，请确保组成IRF的SR8800-X使用的主控板丝印完全相同，否则不能形成IRF。 建立IRF前，请确保组成IRF的SR8800-X使用的交换网板为B类交换网板或D类交换网板，否则不能形成IRF。 IRF中所有成员设备的软件版本必须相同，如果有软件版本不同的设备要加入IRF，请确保

IRF的启动文件同步加载功能处于使能状态。

2. IRF连接限制

本设备上与IRF-Port1绑定的IRF物理端口只能和邻居成员设备IRF-Port2口上绑定的IRF物理端口相连，本设备上与IRF-Port2口绑定的IRF物理端口只能和邻居成员设备IRF-Port1口上绑定的IRF物理端口相连，如表1所示。否则，不能形成IRF。

3. IRF最大成员设备数限制

本系列路由器最多支持使用两台设备建立IRF。

4 两台成员设备的IRF配置举例

4.1 组网需求

? 如所示，Device A为公司的核心设备，但由于公司网络规模日益增大，汇聚层SW设备

扩展至N台，Device A单台设备的转发能力已无法达到公司网络的需求。为了拓展核心设备的转发能力，又尽量不改变现有网络。现公司希望增加Device B，与Device A组成IRF，来满足当前网络的需求。

? IRF的上行设备（Router A和Router B）为公司网络的出口路由器；IRF的下行交换机

（SW 1、SW 2等）为各个服务器集群的汇聚层设备。

4.2 配置思路

?

为避免成员设备的单点故障影响到正常的业务转发，可在IRF中配置跨框聚合端口进行业务转发。
