[url=]1. 组网需求(1) 需求分析 · 公司A为知名网络公司的数据中心,需要管理规模庞大的服务器和存储设备; · 公司B为金融企业的数据中心,对于网络的稳定性及安全性有极高的要求,需要独立的网络环境,不受其他公司的影响。 (2) 网络规划 为提高设备的转发性能和可靠性,同时节省成本,使用IRF+MDC技术,使两个公司共同使用一个IRF。 将Master和Standby两台成员设备组成IRF,IRF拥有四块接口板,接口板2和3分别位于Master设备的2号槽和3号槽,接口板2和3分别位于Standby成员设备的2,3号槽,每个接口板有16个万兆以太网口; 将IRF虚拟成两台独立的设备:MDC A,MDC B,每个MDC相当于一个独立的物理设备,MDC之间相互隔离,不能直接通信,具有很高的安全性,可满足公司B的需求; 各MDC可以独享设备的表项资源,满足公司A对表项资源的需求。 [/url]

2、配置步骤
[url=](1) 在缺省MDC中组建IRF,关于缺省MDC中组建IRF的详细步骤介绍,请参见“虚拟化技术配置指导”中的“IRF”。 (2) 配置IRF的网管口的IP地址、使能Telnet服务等基础配置,供用户远程登录缺省MDC。 <IRF> system-view [IRF] interface M-GigabitEthernet 1/0/0/0 [IRF-M-GigabitEthernet1/0/0/0] ip address 192.168.0.250 16 [IRF-M-GigabitEthernet1/0/0/0] quit [IRF] telnet server enable (3) 取消缺省MDC上需要划分给非缺省MDC的接口板使用权限。 [IRF] mdc Admin [IRF-mdc-1-Admin] undo location chassis 1 slot 2 The configuration associated with the specified slot of MDC will be lost.
