H3C Constructing Small - and Medium - Sized Enterprise Network Sample Questions:

1. 两台空配置的 MSR 路由器 MSR-1 、 MSR-2 通过各自的 S1/0 接口背靠背互连,各自的 GigabitEthernet0/0 接口
分别连接客户端主机 HostA 和 HostB :
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
然后在两台路由器上分别做了如下的配置:
MSR-1 上的配置:
[MSR-1]interface GigabitEthernet 0/0
[MSR-1-GigabitEthernet0/0]ip add 192.168.1.1 24
[MSR-1]interface Serial 1/0
[MSR-1-Serial1/0]ip address 30.3.3.1 30
[MSR-1]rip
[MSR-1-rip-1]network 0.0.0.0
MSR-2 上的配置:
[MSR-2]interface GigabitEthernet 0/0
[MSR-2-GigabitEthernet0/0] ip address 10.10.10.1 24
[MSR-2]interface Serial 1/0
[MSR-2-Serial1/0]ip address 30.3.3.2 30
[MSR-2]rip
[MSR-2-rip-1]network 10.10.10.0
[MSR-2-rip-1]network 30.3.3.1
根据以上配置后,两台路由器之间的广域网接口可以互通,网络中其他物理链路良好,两台主机 HostA 、
