 redistribute rip subnets

 network 3.3.3.0 0.0.0.255 area 1

 network 23.1.1.0 0.0.0.255 area 1

router rip

 version 2

 network 34.0.0.0

 no auto-summary

R4配置

 ip address 4.4.4.4 255.255.255.0

interface Serial0/0

 ip address 34.1.1.4 255.255.255.0

router rip

 version 2

 network 4.0.0.0

 network 34.0.0.0

 no auto-summary

4、域间汇总

在R3上建立四个环回口，并宣告进Area1

1o16:192.168.16.1/24

1o17:192.168.17.1/24

1o18:192.168.18.1/24

1o19:192.168.19.1/24

R3配置

interface Loopback16

 ip address 192.168.16.1 255.255.255.0        

interface Loopback17

 ip address 192.168.17.1 255.255.255.0

interface Loopback18

 ip address 192.168.18.1 255.255.255.0

interface Loopback19

 ip address 192.168.19.1 255.255.255.0

router ospf 110

 router-id 8.8.8.3

 network 192.168.16.0 0.0.0.255 area 1

 network 192.168.17.0 0.0.0.255 area 1

 network 192.168.18.0 0.0.0.255 area 1

 network 192.168.19.0 0.0.0.255 area 1

此时R1收到的是4条明细路由，我们在R2上做域间汇总。

注：域间汇总要在本局域内的所有ABR上进行汇总。

5、域×××总
