华小智问道IE面试 | IRF配置示例

只见华小阮老师走上讲台，将目光落在了华小智身上，亲切的说道：“前面我们已经对IRF及MAD多主检测的相关理论进行了充分的了解，接下来让我们请华小智同学为我们进行IRF配置示例的演示。”今天我们主要关注IRF配置及通过BFD MAD实现多主检测，配置示例需要用到的环境如图1所示。SWA-1和SWA-2组成IRF堆叠系统，其接口XGE1/0/50和XG1/0/51为物理堆叠口，G1/0/9接口为BFD MAD检测接口；IRF堆叠系统通过三层聚合接口上联RT1，通过二层聚合接口下联SWB。

图1接下来，我们完成相关的配置示例。第一步：完成SWA-1和SWA-2的IRF配置。在SWA-1上的配置：[SWA-1]irf member 1 priority 32     //修改member 1设备上的优先级为32（使其角色竞选时胜出）[SWA-1]interface range Ten-GigabitEthernet 1/0/50 Ten-GigabitEthernet 1/0/51[SWA-1-if-range]shutdown          //关闭物理堆叠口[SWA-1-if-range]quit[SWA-1]irf-port 1/2                //创建逻辑堆叠口[SWA-1-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50  //将物理堆叠口绑定到逻辑堆叠口[SWA-1-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/51[SWA-1-irf-port1/2]quit            [SWA-1]interface range Ten-GigabitEthernet 1/0/50 Ten-GigabitEthernet 1/0/51[SWA-1-if-range]undo shutdown     //开启物理堆叠口[SWA-1-if-range]quit[SWA-1]save f                    //保存配置[SWA-1]irf-port-configuration active  //激活IRF堆叠口配置--------------------------------------------------------------------------------------------------------------------------[SWA-2]irf member 1 renumber 2    //为设备指定新的设备编号Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:yPlease reboot the device for the new member ID to take effect. //提示重启设备新编号才生效[SWA-2]quit<SWA-2>reboot                  //重启设备，记得保存配置[SWA-2]interface range Ten-GigabitEthernet 2/0/50 Ten-GigabitEthernet 2/0/51[SWA-2-if-range]shutdown         //关闭物理堆叠口[SWA-2-if-range]quit[SWA-2]irf-port 2/1[SWA-2-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/50  //将物理堆叠口绑定到逻辑堆叠口[SWA-2-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/51[SWA-2-irf-port2/1]quit[SWA-2]interface range Ten-GigabitEthernet 2/0/50 Ten-GigabitEthernet 2/0/51[SWA-2-if-range]undo shutdown     //开启物理堆叠口[SWA-2-if-range]quit[SWA-2]save f                    //保存配置[SWA-2]irf-port-configuration active  //激活IRF堆叠口配置此时，因为SWA-1的irf优先级为32且先配置完成，SWA-2的irf优先级1，所以当在SWA-2上激活IRF堆叠口的配置，由于竞选失败，SWA-2会自动重启并以从设备的角色加入到IRF中。在SWA-1上通过命令“display irf”可以查询到IRF堆叠系统已经组建成功。<SWA-1>display irfMemberID    Role    Priority     CPU-Mac          Description *+1        Master   32         688f-b95d-0204      ---   2        Standby  1          688f-becc-0304       ----------------------------------------------------- *

Auto upgrade                : yes Mac persistent              : 6 min Domain ID                   : 0第二步：实现BFD MAD检测。通过IRF堆叠系统并进行相关的配置如下：[SWA-1]vlan 4094                //创建BFD MAD检测vlan[SWA-1-vlan4094]port GigabitEthernet 1/0/9          //向vlan4094中添加端口[SWA-1-vlan4094]port GigabitEthernet 2/0/9[SWA-1-vlan4094]quit[SWA-1]interface range GigabitEthernet 1/0/9 GigabitEthernet 2/0/9[SWA-1-if-range]undo stp enable      //关闭BFD MAD检测接口stp功能[SWA-1-if-range]quit[SWA-1]interface Vlan-interface 4094[SWA-1-Vlan-interface4094]mad bfd enable     //使能BFD

mad地址[SWA-1-Vlan-interface4094]quit第三步：完成IRF堆叠系统通过三层聚合接口上联RT1。在IRF堆叠系统上的配置：[SWA-1]interface range GigabitEthernet 1/0/1 GigabitEthernet 2/0/1[SWA-1-if-range]port link-mode route   //将接口模式有bridge（二层）修改为route（三层）[SWA-1-if-range]quit[SWA-1]interface Route-Aggregation 1[SWA-1-Route-Aggregation1]link-aggregation mode dynamic   //配置为动态链路聚合[SWA-1-Route-Aggregation1]quit[SWA-1]interface range GigabitEthernet 1/0/1 GigabitEthernet 2/0/1[SWA-1-if-range]port link-aggregation group 1      //将成员接口添加到聚合组[SWA-1-if-range]quit------------------------------------------------在RT1上的配置：[RT1]interface Route-Aggregation 1[RT1-Route-Aggregation1]link-aggregation mode dynamic [RT1-Route-Aggregation1]quit[RT1]interface range GigabitEthernet 0/0 GigabitEthernet 0/1[RT1-if-range]port link-aggregation group 1[RT1-if-range]quit//通过命令“display link-aggregation
