此时再度在路由器R1上做先前示例中的相同汇总地址配置，如下所示：
```
R1(config)#int s0/0
R1(config-if)#ip summary-address eigrp 150 10.0.0.0 255.252.0.0
R1(config-if)#exit
```
那么此时基于此配置，该汇总路由就以它所包含的所有路由中的最小度量值，而放入到EIGRP拓扑表和IP路由表中（Based on this configuration, the summary route is placed into the EIGRP topology table and the IP routing table with a metric equal to the lowest metric of all routes that it encompasses）。而根据前面所展示的`show ip eigrp topology`命令的输出，该汇总地址将获得到与`10.3.3.0/24`前缀相同的度量值，如下所示：
```
R1#show ip eigrp topology
IP-EIGRP Topology Table for AS(150)/ID(10.3.3.1)
