如果你对管理间距和量度不太熟悉,你即便是看到了这些参数,也不会重视它们。如果你输入一条show ip route命令,你就会注意到在路由器后面的括弧里出现这两个参数。这里为一个例子:
O 10.1.103.0/24 [110/791] via 10.1.100.2, 00:39:44, Serial1/0:0.21
在这一例子中,110表示管理间距,791代表量度。通过输入相同的show ip route命令并指定路由器的方式,你可以看到更详细的信息,这有一个例子:
Router# show ip route 10.1.103.0
Routing entry for 10.1.103.0/24
