【解析】
【问题1】解析：华为交换机基本配置命令，需要记住常考如vlan trunk，stp，dhcp等配置。另外注意从表中找到对应地址即可。【问题 2】解析：因为SW1GE0/0/2接口PVID为200与之对应SW2上GE0/0/24接口PVID也需要为200，否则VLAN 200业务数据通不过中继口。【问题 3】解析：R1配置如下：＜Huawei>system-view Enter system view, return user view with Ctrl+Z.[Huawei]sysname R1[R1]interface Dialer 1[R1-Dialer1]dialer user user01[R1-Dialer1]dialer bundle 1[R1-Dialer1]ppp chap user user01[R1-Dialer1]ppp chap password cipher huawei@123[R1-Dialer1]ip address ppp-negotiate[R1-Dialer1]quit[R1]interface GigabitEthernet 0/0/0[R1-GigabitEthernet0/0/0]pppoe-client dial-bundle-number 1[R1-GigabitEthernet0/0/0]quit[R1]acl number 2000[R1-acl-basic-2000]rule permit source 192.168.200.0 0.0.0.255 [R1-acl-basic-2000]rule permit source 192.168.201.0 0.0.0.255[R1-acl-basic-2000]quit[R1]interface Dialer 1[R1-Dialer1]nat outbound 2000[R1-Dialer1]quit[R1]ip route-static 0.0.0.0 0 Dialer 1[R1]interface GigabitEthernet 0/0/1[R1-GigabitEthernet0/0/1]ip address 172.16.0.1 30
