配置思路

采用如下的思路配置：

  1. 配置SwitchA、SwitchB、SwitchC建立M-LAG系统。
    • 配置SwitchB和SwitchC的V-STP。
    • 配置SwitchB和SwitchC的DFS Group并绑定管理网口的IP地址。
    • 配置SwitchB和SwitchC之间的peer-link链路。
    • 配置SwitchB和SwitchC的M-LAG成员接口，SwitchA的Eth-Trunk接口。
    • 配置SwitchB和SwitchC的Monitor Link功能。

      Monitor Link将上行接口和下行接口关联，避免因上行链路故障导致用户侧流量无法转发而丢弃。

  2. 配置OSPF接入M-LAG。
    • 配置SwitchB、SwitchC、SwitchD的路由协议OSPF，实现网络三层互通。
    • 配置SwitchB和SwitchC的动态路由OSPF接入M-LAG的IPv4地址。

      SwitchB和SwitchC上需要配置不一样的M-LAG IPv4地址，否则会导致路由协议邻居建立不起来。

    • 配置SwitchA和M-LAG成员设备建立动态路由OSPF的IP地址。
  3. 配置OSPFv3接入M-LAG。
    • 配置SwitchB、SwitchC、SwitchD的路由协议OSPFv3，实现网络三层互通。
    • 配置SwitchB和SwitchC的动态路由OSPFv3接入M-LAG的Link-local地址。

      SwitchB和SwitchC上需要配置不一样的M-LAG Link-local地址，否则会导致路由协议邻居建立不起来。

    • 配置SwitchA和M-LAG成员设备建立动态路由OSPFv3的IPv6地址。
  4. 配置BGP接入M-LAG。
    • 配置SwitchB、SwitchC、SwitchD的路由协议BGP，实现网络三层互通。
    • 配置SwitchB和SwitchC的动态路由BGP接入M-LAG的IPv4地址。

      SwitchB和SwitchC上需要配置不一样的M-LAG IPv4地址，否则会导致路由协议邻居建立不起来。

    • 配置SwitchA和M-LAG成员设备（SwitchB、SwitchC）建立动态路由BGP的对等体。
  5. 配置BGP4+接入M-LAG。
    • 配置SwitchB、SwitchC、SwitchD的路由协议BGP4+，实现网络三层互通。
    • 配置SwitchB和SwitchC的动态路由BGP接入M-LAG的IPv6地址。

      SwitchB和SwitchC上需要配置不一样的M-LAG IPv6地址，否则会导致路由协议邻居建立不起来。

    • 配置SwitchA和M-LAG成员设备（SwitchB、SwitchC）建立动态路由BGP4+的对等体和引入路由。

操作步骤

  1. 配置SwitchA、SwitchB、SwitchC建立M-LAG系统。
    1. 配置SwitchB和SwitchC的V-STP。

       

      # 配置SwitchB。SwitchC的配置与SwitchB类似，这里不再赘述。

      <HUAWEI> system-view
[~HUAWEI] sysname SwitchB
[*HUAWEI] commit
[~SwitchB] stp mode rstp
[*SwitchB] stp v-stp enable
[*SwitchB] commit

       

    2. 配置SwitchB和SwitchC的DFS Group并绑定管理网口的IP地址。

       

      SwitchB和SwitchC管理网口需要保证能够三层互通。

      # 配置SwitchB。SwitchC的配置与SwitchB类似，这里不再赘述。

      [~SwitchB] dfs-group 1
[*SwitchB-dfs-group-1] source ip 10.200.1.1
[*SwitchB-dfs-group-1] quit
[*SwitchB] commit

       

    3. 配置SwitchB和SwitchC之间的peer-link链路。

       

      # 配置SwitchB。SwitchC的配置与SwitchB类似，这里不再赘述。

      [~SwitchB] interface eth-trunk 1
[*SwitchB-Eth-Trunk1] mode lacp-static
[*SwitchB-Eth-Trunk1] trunkport 10ge 1/0/4
[*SwitchB-Eth-Trunk1] trunkport 10ge 1/0/5
[*SwitchB-Eth-Trunk1] peer-link 1
[*SwitchB-Eth-Trunk1] quit
[*SwitchB] commit

       

    4. 配置SwitchB和SwitchC的M-LAG成员接口，SwitchA的Eth-Trunk接口。

       

      # 配置SwitchB。SwitchC的配置与SwitchB类似，这里不再赘述。

      [~SwitchB] interface eth-trunk 10
[*SwitchB-Eth-Trunk10] mode lacp-static
[*SwitchB-Eth-Trunk10] port link-type trunk
[*SwitchB-Eth-Trunk10] lacp mixed-rate link enable
[*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

      # 配置SwitchA。

      <HUAWEI> system-view
[~HUAWEI] sysname SwitchA
[*HUAWEI] commit
[~SwitchA] interface eth-trunk 10
[*SwitchA-Eth-Trunk10] mode lacp-static
[*SwitchA-Eth-Trunk10] port link-type trunk
[*SwitchA-Eth-Trunk10] trunkport 10ge 1/0/1 to 1/0/4
[*SwitchA-Eth-Trunk10] quit
[*SwitchA] commit

       

    5. 配置SwitchB和SwitchC的Monitor Link功能。

       

      # 配置SwitchB。SwitchC的配置与SwitchB类似，这里不再赘述。

      [~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

       

  2. 配置OSPF接入M-LAG。
    1. 配置SwitchB、SwitchC、SwitchD的路由协议OSPF，实现网络三层互通。

       

      # 配置SwitchB。SwitchC和SwitchD的配置与SwitchB类似，这里不再赘述。配置OSPF时，注意需要发布32位Loopback接口地址。

      [~SwitchB] interface loopback 1
[*SwitchB-LoopBack1] ip address 10.2.2.2 32
[*SwitchB-LoopBack1] quit
[*SwitchB] interface loopback 2
[*SwitchB-LoopBack2] ip address 10.3.3.3 32
[*SwitchB-LoopBack2] quit
[*SwitchB] interface 10ge 1/0/1
[*SwitchB-10GE1/0/1] undo portswitch
[*SwitchB-10GE1/0/1] ip address 192.168.1.1 24
[*SwitchB-10GE1/0/1] quit
[*SwitchB] ospf 1 router-id 11.1.1.1
[*SwitchB-ospf-1] area 0
[*SwitchB-ospf-1-area-0.0.0.0] network 10.2.2.2 0.0.0.0
[*SwitchB-ospf-1-area-0.0.0.0] network 10.3.3.3 0.0.0.0
[*SwitchB-ospf-1-area-0.0.0.0] network 192.168.1.0 0.0.0.255
[*SwitchB-ospf-1-area-0.0.0.0] quit
[*SwitchB-ospf-1] quit
[*SwitchB] commit

      OSPF成功配置后，SwitchB、SwitchC、SwitchD之间可通过OSPF协议发现对方的Loopback接口的IP地址，并能互相ping通。

       

    2. 配置SwitchB和SwitchC的动态路由OSPF接入M-LAG的IPv4地址。

       

      # 配置SwitchB。

  3. 配置OSPFv3接入M-LAG。
    1. 配置SwitchB、SwitchC、SwitchD的路由协议OSPFv3，实现网络三层互通。

       

      # 配置SwitchB。SwitchC和SwitchD的配置与SwitchB类似，这里不再赘述。
