Refer to the exhibit. An engineer is updating the R1 configuration to connect a new server to the management network. The PCs on the management network must be blocked from pinging the default gateway of the new server. Which command must be configured on R1 to complete the task?

[*]A. R1(config)#ip route 172.16.2.0.255.255.255.0 192.168.1.15
[*]B. R1(config)#ip route 172.16.2.2 255.255.255.248 gi0/1
[*]C. R1(config)#ip route 172.16.2.2 255.255.255.255 gi0/0
[*]D. R1(config)#ip route 172.16.2.0 255.255.255.0 192.168.1.5


就是要阻止pc ping服务器的default gateway吗？我不太明白如何确认服务器的默认gateway。

感谢大佬们的回复，我懂了，其实就是要防止pc ping到server，就让server的出口只到r1的接口，这样就相当于，server发的包到不了pc
