显示ip dhcp池名的不一致行为

Question

显示ip池Mitarbeiter10提供以下输出：

R1#show ip dhcp pool Mitarbeiter10 
Pool Mitarbeiter10 :
Utilization mark (high/low)    : 100 / 0
Subnet size (first/next)       : 0 / 0 
Total addresses                : 254
Leased addresses               : 1
Excluded addresses             : 1
Pending event                  : none

1 subnet is currently in the pool
Current index        IP address range                    Leased/Excluded/Total
192.168.10.1         192.168.10.1     - 192.168.10.254    1    / 1     / 254

这指的是以下网络

可以到达该网络的路由器接口为ip 192.168.10.1。为什么这个ip是dhcp池的一部分？我知道，默认情况下，路由器将从dhcp池中排除分配给其接口的地址。但是，当前的索引不就是分配给下一个客户机的ip地址吗？

同时显示run _i排除-地址不列出任何排除的地址。

路由器配置：

ip dhcp pool Mitarbeiter10

Answer 1

ip dhcp pool Mitarbeiter10
 network 192.168.10.0 255.255.255.0

该配置将所有合法子网地址添加到池中。然而，路由器本身的地址被隐式地排除在外，所以它永远不会提供给客户端。
