OSPF 的高级路由配置

1.实验拓扑：

2.实验目的：2.1按照拓扑图正确连接4台路由器
2.2完成NSSA的配置，进行路由重分发，并进行验证.

                      2.3   (Config-router)#area 51 nssa
                               (configt)#router rip
                             (Config-router)#redistribute ospf 7 metric 10
                               (config)#router ospf 8
                            (Config-router)# redistribute rip metric 200 subnets

3.操作详细配置
step 1.配置路由器SH1，SH3，GZ1，BJ的相应接口IP地址
路由器SH1配置如下：

Router(config)#HO SH1
SH1(config)#int lo 0
SH1(config-if)#ip add 192.168.64.1 255.255.255.0
SH1(config-if)#no shut
SH1(config-if)#exit
SH1(config)#int lo 5
SH1(config-if)#ip add 10.0.0.6 255.255.255.252
SH1(config-if)#no shut
SH1(config-if)#exit
SH1(config)#int f0/0
SH1(config-if)#ip add 192.168.1.1 255.255.255.0
SH1(config-if)#no shut
SH1(config-if)#exit
SH1(config)#

路由器SH3配置如下：

Router>
Router>EN
Router#CONF T
Router(config)#HO SH3
SH3(config)#int f0/0
SH3(config-if)#ip add 192.168.1.3 255.255.255.0
SH3(config-if)#no shut
SH3(config-if)#exit
SH3(config)#int lo 0
SH3(config-if)#ip add 192.168.3.1 255.255.255.0
SH3(config-if)#no shut
SH3(config-if)#exit
SH3(config)#int s1/0
SH3(config-if)#ip add 192.168.224.1 255.255.255.252
SH3(config-if)#no shut
SH3(config-if)#exit
SH3(config)#

路由器GZ1配置如下：

Router>en
Router#conf t
Router(config)#ho GZ1
GZ1(config)#int s1/0
GZ1(config-if)#ip add 192.168.224.2 255.255.255.252
GZ1(config-if)#no shut
GZ1(config-if)#exit
GZ1(config)#int f0/0
GZ1(config-if)#ip add 192.168.5.1 255.255.255.0
GZ1(config-if)#no shut
GZ1(config-if)#exit
GZ1(config)#

路由器BJ配置如下：

Router>EN
Router#CONF T
Router(config)#HO BJ
BJ(config)#int f0/0
BJ(config-if)#ip add 192.168.5.2 255.255.255.0
BJ(config-if)#no shut
BJ(config-if)#end

step2 .配置OSPF路由协议

路由器SH1配置如下：

SH1(config)#router ospf 7
SH1(config-router)#net 192.168.64.0 0.0.0.255 area 1
SH1(config-router)#net 192.168.1.0 0.0.0.255 area 0
SH1(config-router)#exit
SH1(config)#

路由器SH3配置如下:

SH3(config)#router ospf 8
SH3(config-router)#net 192.168.1.0 0.0.0.255 area 0
SH3(config-router)#net 192.168.3.0 0.0.0.255 area 0
SH3(config-router)#net 192.168.224.0 0.0.0.3 area 51
SH3(config-router)#end

路由器GZ1配置如下：

GZ1(config)#router ospf 9
GZ1(config-router)#net 192.168.224.0 0.0.0.3 area 51
GZ1(config-router)#end

验证:

SH1(config)#do ping 192.168.1.3

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.3, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 64/113/200 ms

SH1#ping 192.168.224.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.224.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 216/256/296 ms

step3 .配置 NSSA并进行路由重分发

路由器GZ1配置如下：

配置RIP

GZ1(config)#router rip
GZ1(config-router)#net 192.168.5.0

路由器BJ配置如下：
