change loop count is 0, and the maximum number of records is 4095.
注意：用display valn 查看当前划分是否正确，以防出错带来不必要的麻烦
如图所示：
四．给两台交换机配置网关
以下是详细步骤：
LSW１
[Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.30.1
[Huawei]
Oct 16 2013 17:45:59-08:00 Huawei DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.
25.191.3.1 configurations have been changed. The current change number is 12, the
change loop count is 0, and the maximum number of records is 4095.
LSW２

[Huawei]
Oct 16 2013 17:46:48-08:00 Huawei DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.
25.191.3.1 configurations have been changed. The current change number is 12, the
change loop count is 0, and the maximum number of records is 4095.
五．在路由器上创建子接口
以下是详细步骤：
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]interface GigabitEthernet 0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dot1q t
[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 10
[Huawei-GigabitEthernet0/0/0.1]ip add 192.168.1.1 24
Oct 16 2013 15:05:30-05:13 Huawei %%01IFNET/4
[Huawei-GigabitEthernet0/0/0.1]/LINK_STATE(l)[0]:The line protocol IP on the interface GigabitEthernet0/0/0.1 has entered the UP state.
[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.1]int g0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]dot1q termination vid 20
[Huawei-GigabitEthernet0/0/0.2]ip add 192.168.2.1 24
Oct 16 2013 15:07:41-05:13 Huawei %%0
[Huawei-Gigabi1IFNET/4/LINK_STATE(l)[1]:The linetEthernet0/0/0.2] protocol IP on the interface GigabitEthernet0/0/0.2 has entered the UP state.
[Huawei-GigabitEthernet0/0/0.2]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.2]int g0/0/0.3
[Huawei-GigabitEthernet0/0/0.3]dot1q termination vid 1
[Huawei-GigabitEthernet0/0/0.3]ip add 192.168.30.1 24
Oct 16 2013 15:08:28
[Huawei-Gigabit-05:13 HuawEthernetei %%01IFNET/4/LINK_STATE(0/0/0.3]l)[2]:The line protocol IP on the interface GigabitEthernet0/0/0.3 has entered the UP state.
[Huawei-GigabitEthernet0/0/0.3]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.3]
注意别忘了开启ARP ＭＡＣ地址请求！！！
六．创建DHCP地址池
详细步骤如下：
[Huawei]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[Huawei]ip pool CTO
Info: It's successful to create an IP address pool.
[Huawei-ip-pool-CTO]network 192.168.1.0 mask 24
七验证：
如图：
如果VLAN 20的成员没有自动获取DHCP成功，则是单臂路由没有做，做了即可
注意！
做单臂路由别忘了将
也改为中继口，本人在做的时候就忘了，结果造成了不必要的麻烦
就此完成
有错误及时更正
