    配置交换机双归接入IP 网络示例(V-STP 方式)(推荐)

      如图4-23所示,通过配置M-LAG双归接入IP网络可以满足以下要求:

      ● 当一条接入链路发生故障时,流量可以快速切换到另一条链路,保证可靠性。

      ● 为了高效利用带宽,两条链路同时处于active状态,可实现使用负载分担的方式转发流量。

       

    1.配置思路

      采用如下的思路配置M-LAG双归接入IP网络:

      1. 在Switch上配置上行接口绑定在一个Eth-Trunk中。

      2. 分别在SwitchA和SwitchB上配置V-STP、DFS Group、peer-link和M-LAG接口。

      3. 分别在SwitchA和SwitchB上配置VLANIF接口IP地址和MAC地址,作为接入设备的双活网关。

      4. 分别在SwitchA、SwitchB和SwitchC上配置OSPF功能,保证三层互通。

        说明:在V-STP场景下,为防止接口因生成树协议计算结果被阻塞,可以通过配置主接口实现三层互通或者去使能IP网络侧的生成树协议。

      5. 分别在SwitchA和SwitchB上配置Monitor Link关联上行接口和下行接口,避免因上行链路故障导致用户侧流量无法转发而丢弃。

    2.操作步骤

      1.在Switch上配置上行接口绑定在一个Eth-Trunk中  

    <HUAWEI> system-view
    [~HUAWEI] sysname Switch
    [*HUAWEI] commit
    [~Switch] vlan batch 11
    [*Switch] interface eth-trunk 20
    [*Switch-Eth-Trunk20] mode lacp-static
    [*Switch-Eth-Trunk20] port link-type trunk
    [*Switch-Eth-Trunk20] port trunk allow-pass vlan 11
    [*Switch-Eth-Trunk20] trunkport 10ge 1/0/1 to 1/0/4
    [*Switch-Eth-Trunk20] quit
    [*Switch] commit

      2.分别在SwitchA和SwitchB上配置V-STP、DFS Group、peer-link和M-LAG接口

      1)配置SwitchA。  

    <HUAWEI> system-view
    [~HUAWEI] sysname SwitchA
    [*HUAWEI] commit
    [~SwitchA] stp mode rstp
    [~SwitchA] stp bridge-address 1-1-1
    [*SwitchA] stp v-stp enable
    [*SwitchA] interface loopback 0
    [*SwitchA-LoopBack0] ip address 10.1.1.1 32
    [*SwitchA-LoopBack0] quit
    [*SwitchA] dfs-group 1
    [*SwitchA-dfs-group-1] source ip 10.1.1.1
    [*SwitchA-dfs-group-1] priority 150
    [*SwitchA-dfs-group-1] quit
    [*SwitchA] interface eth-trunk 1
    [*SwitchA-Eth-Trunk1] trunkport 10ge 1/0/4
    [*SwitchA-Eth-Trunk1] trunkport 10ge 2/0/5
    [*SwitchA-Eth-Trunk1] mode lacp-static
    [*SwitchA-Eth-Trunk1] peer-link 1
    [*SwitchA-Eth-Trunk1] quit
    [*SwitchA] vlan batch 11
    [*SwitchA] interface eth-trunk 10
    [*SwitchA-Eth-Trunk10] mode lacp-static
    [*SwitchA-Eth-Trunk10] port link-type trunk
    [*SwitchA-Eth-Trunk10] port trunk allow-pass vlan 11
    [*SwitchA-Eth-Trunk10] trunkport 10ge 1/0/2
    [*SwitchA-Eth-Trunk10] trunkport 10ge 1/0/3
    [*SwitchA-Eth-Trunk10] dfs-group 1 m-lag 1
    [*SwitchA-Eth-Trunk10] quit
    [*SwitchA] commit

      2)配置SwitchB  

    <HUAWEI> system-view
    [~HUAWEI] sysname SwitchB
    [*HUAWEI] commit
    [~SwitchB] stp mode rstp
    [~SwitchB] stp bridge-address 1-1-1
    [*SwitchB] stp v-stp enable
    [*SwitchB] interface loopback 0
    [*SwitchB-LoopBack0] ip address 10.1.1.2 32
    [*SwitchB-LoopBack0] quit
    [*SwitchB] dfs-group 1
    [*SwitchB-dfs-group-1] source ip 10.1.1.2
    [*SwitchB-dfs-group-1] priority 120
    [*SwitchB-dfs-group-1] quit
    [*SwitchB] interface eth-trunk 1
    [*SwitchB-Eth-Trunk1] trunkport 10ge 1/0/4
    [*SwitchB-Eth-Trunk1] trunkport 10ge 2/0/5
    [*SwitchB-Eth-Trunk1] mode lacp-static
    [*SwitchB-Eth-Trunk1] peer-link 1
    [*SwitchB-Eth-Trunk1] quit
    [*SwitchB] vlan batch 11
    [*SwitchB] interface eth-trunk 10
    [*SwitchB-Eth-Trunk10] mode lacp-static
    [*SwitchB-Eth-Trunk10] port link-type trunk
    [*SwitchB-Eth-Trunk10] port trunk allow-pass vlan 11
    [*SwitchB-Eth-Trunk10] trunkport 10ge 1/0/2
    [*SwitchB-Eth-Trunk10] trunkport 10ge 1/0/3
    [*SwitchB-Eth-Trunk10] dfs-group 1 m-lag 1
    [*SwitchB-Eth-Trunk10] quit
    [*SwitchB] commit

      3)分别在SwitchA和SwitchB上配置VLANIF接口IP地址和MAC地址,作为接入设备的双活网关两端的虚拟IP和虚拟MAC配置要求完全一致,目的是为M-LAG提供相同的虚拟IP和虚拟MAC。

    # 配置SwitchA。
    [~SwitchA] interface vlanif 11
    [*SwitchA-Vlanif11] ip address 10.2.1.1 24
    [*SwitchA-Vlanif11] mac-address 0000-5e00-0101
    [*SwitchA-Vlanif11] quit
    [*SwitchA] commit
    # 配置SwitchB。
    [~SwitchB] interface vlanif 11
    [*SwitchB-Vlanif11] ip address 10.2.1.1 24
    [*SwitchB-Vlanif11] mac-address 0000-5e00-0101
    [*SwitchB-Vlanif11] quit
    [*SwitchB] commit

      4)分别在SwitchA、SwitchB和SwitchC上配置OSPF功能,保证三层互通  

    # 配置SwitchA。
    [~SwitchA] interface 10ge 1/0/1
    [~SwitchA-10GE1/0/1] undo portswitch
    [*SwitchA-10GE1/0/1] ip address 10.3.1.1 24
    [*SwitchA-10GE1/0/1] quit
    [*SwitchA] ospf 1
    [*SwitchA-ospf-1] area 0
    [*SwitchA-ospf-1-area-0.0.0.0] network 10.1.1.1 0.0.0.0

    [*SwitchA-ospf-1-area-0.0.0.0] network 10.3.1.0 0.0.0.255
    [*SwitchA-ospf-1-area-0.0.0.0] quit
    [*SwitchA-ospf-1] quit
    [*SwitchA] commit
    # 配置SwitchB。
    [~SwitchB] interface 10ge 1/0/1
    [~SwitchB-10GE1/0/1] undo portswitch
    [*SwitchB-10GE1/0/1] ip address 10.4.1.1 24
    [*SwitchB-10GE1/0/1] quit
    [*SwitchB] ospf 1
    [*SwitchB-ospf-1] area 0
    [*SwitchB-ospf-1-area-0.0.0.0] network 10.1.1.2 0.0.0.0
    [*SwitchB-ospf-1-area-0.0.0.0] network 10.2.1.0 0.0.0.255
    [*SwitchB-ospf-1-area-0.0.0.0] network 10.4.1.0 0.0.0.255
    [*SwitchB-ospf-1-area-0.0.0.0] quit
    [*SwitchB-ospf-1] quit
    [*SwitchB] commit
    # 配置SwitchC。
    <HUAWEI> system-view
    [~HUAWEI] sysname SwitchC
    [*HUAWEI] commit
    [~SwitchC] interface 10ge 1/0/1
    [~SwitchC-10GE1/0/1] undo portswitch
    [*SwitchC-10GE1/0/1] ip address 10.3.1.2 24
    [*SwitchC-10GE1/0/1] quit
    [*SwitchC] interface 10ge 1/0/2
    [*SwitchC-10GE1/0/2] undo portswitch
    [*SwitchC-10GE1/0/2] ip address 10.4.1.2 24
    [*SwitchC-10GE1/0/2] quit
    [*SwitchC] ospf 1
    [*SwitchC-ospf-1] area 0
    [*SwitchC-ospf-1-area-0.0.0.0] network 10.3.1.0 0.0.0.255
    [*SwitchC-ospf-1-area-0.0.0.0] network 10.4.1.0 0.0.0.255
    [*SwitchC-ospf-1-area-0.0.0.0] quit
    [*SwitchC-ospf-1] quit
    [*SwitchC] commit

      5)分别在SwitchA和SwitchB上配置Monitor Link关联上行接口和下行接口  

    # 配置SwitchA。
    [~SwitchA] monitor-link group 1
    [*SwitchA-mtlk-group1] port 10ge 1/0/1 uplink
    [*SwitchA-mtlk-group1] port eth-trunk 10 downlink 1
    [*SwitchA-mtlk-group1] quit
    [*SwitchA] commit
    # 配置SwitchB。
    [~SwitchB] monitor-link group 1
    [*SwitchB-mtlk-group1] port 10ge 1/0/1 uplink
    [*SwitchB-mtlk-group1] port eth-trunk 10 downlink 1
    [*SwitchB-mtlk-group1] quit
    [*SwitchB] commit

      6)验证配置结果

      执行命令display dfs-group,查看M-LAG的相关信息。

      # 查看DFS Group编号为1的M-LAG信息。

    [~SwitchA] display dfs-group 1 m-lag
    * : Local node
    Heart beat state : OK
    Node 1 *
    Dfs-Group ID : 1
    Priority : 150
    Address : ip address 10.1.1.1
    State : Master
    Causation : -
    System ID : 0025-9e95-7c31
    SysName : SwitchA
    Version : V100R006C00
    Device Type : CE12800
    Node 2
    Dfs-Group ID : 1
    Priority : 120
    Address : ip address 10.1.1.2
    State : Backup
    Causation : -
    System ID : 0025-9e95-7c11
    SysName : SwitchB
    Version : V100R006C00
    Device Type : CE12800

      # 查看SwitchA上的M-LAG信息。  

    [~SwitchA] display dfs-group 1 node 1 m-lag brief
    * - Local node
    M-Lag ID Interface Port State Status Consistency-check
    1 Eth-Trunk 10 Up active(*)-active --
    Failed reason:
    1 -- Relationship between vlan and port is inconsistent
    2 -- STP configuration under the port is inconsistent
    3 -- STP port priority configuration is inconsistent
    4 -- LACP mode of M-LAG is inconsistent
    5 -- M-LAG configuration is inconsistent
    6 -- The number of M-LAG members is inconsistent

      # 查看SwitchB上的M-LAG信息。  

    [~SwitchB] display dfs-group 1 node 2 m-lag brief
    * - Local node
    M-Lag ID Interface Port State Status Consistency-check
    1 Eth-Trunk 10 Up active-active(*) --
    Failed reason:
    1 -- Relationship between vlan and port is inconsistent
    2 -- STP configuration under the port is inconsistent
    3 -- STP port priority configuration is inconsistent
    4 -- LACP mode of M-LAG is inconsistent
    5 -- M-LAG configuration is inconsistent
    6 -- The number of M-LAG members is inconsistent

      通过以上显示信息可以看到,“Heart beat state”的状态是“OK”,表明心跳状态正常;SwitchA作为Node 1,优先级为150,“State”的状态是“Master”;SwitchB作为Node 2,优先级为120,“State”的状态是“Backup”。

      同时“Causation”的状态是“-”,Node 1的“Port State”状态为“Up”,Node 2的“Port State”状态为“Up”,且Node 1和Node 2的M-LAG状态均为“active”,表明M-LAG的配置正确。

    3.配置文件

    interface 10GE1/0/3
    eth-trunk 20
    #
    interface 10GE1/0/4
    eth-trunk 20
    # return

    4.监控M-LAG 运行状况 

      display m-lag troubleshooting { history | current }:查看M-LAG发生故障的原因。该命令最多显示最近100次故障的原因。

      reset m-lag troubleshooting history :清除设备上已有的M-LAG历史故障原因信息。
