基本配置完成后，我们首选来验证一下。

r1#sh ip ro

     130.1.0.0/24 is subnetted, 7 subnets
O E2    130.1.3.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
O E2    130.1.2.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
O E2    130.1.1.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
O E2    130.1.7.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
O E2    130.1.6.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
O E2    130.1.5.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
O E2    130.1.4.0 [110/10] via 192.1.1.2, 00:00:03, Ethernet0/0
     193.1.1.0/24 is variably subnetted, 3 subnets, 2 masks
O IA    193.1.1.192/26 [110/21] via 192.1.1.2, 00:00:48, Ethernet0/0
O IA    193.1.1.128/26 [110/11] via 192.1.1.2, 00:00:48, Ethernet0/0
O IA    193.1.1.0/25 [110/20] via 192.1.1.2, 00:00:48, Ethernet0/0
     192.1.1.0/30 is subnetted, 1 subnets
C       192.1.1.0 is directly connected, Ethernet0/0
     194.1.1.0/30 is subnetted, 1 subnets
O IA    194.1.1.0 [110/30] via 192.1.1.2, 00:39:39, Ethernet0/0

在我们汇总完成后，上述结果里，红、蓝色显示部分将会被取代。方法如下：

区域间汇总：

// R2 //

router os 1

area 0 range 193.1.1.0 255.255.255.0

// R3 //

router os 1

area 0 range 193.1.1.0 255.255.255.0

外部路由汇总：

// R4 //

router os 1

summary-address 130.1.0.0 255.255.248.0

验证如下：

r1#sh ip ro

     130.1.0.0/21 is subnetted, 1 subnets
O E2    130.1.0.0 [110/10] via 192.1.1.2, 00:00:02, Ethernet0/0
O IA 193.1.1.0/24 [110/11] via 192.1.1.2, 00:00:13, Ethernet0/0
     192.1.1.0/30 is subnetted, 1 subnets
C       192.1.1.0 is directly connected, Ethernet0/0
     194.1.1.0/30 is subnetted, 1 subnets
O IA    194.1.1.0 [110/30] via 192.1.1.2, 00:47:19, Ethernet0/0
