ospf配置
本实验需要2600系列路由器两台，交换机一台，PC机两台，console线两条
Step 1 配置路由器
Router1
Router>enable
Router#configure terminal
Router(config)#hostname SHAHE
SHAHE(config)#enable secret class
SHAHE (config)#line console 0
SHAHE (config-line)#password cisco
SHAHE (config-line)#login
SHAHE (config-line)#line vty 0 4
SHAHE (config-line)#password cisco
SHAHE (config-line)#login
SHAHE (config-line)#exit
SHAHE (config)#interface serial 0/0
SHAHE (config-if)#ip address 192.168.15.1 255.255.255.252
SHAHE (config-if)#clock rate 64000
SHAHE (config-if)#no shutdown
SHAHE (config-if)#exit
SHAHE (config)#interface fastEthernet 0/0
SHAHE (config-if)#ip address 192.168.1.129 255.255.255.192
SHAHE (configif)#no shutdown
SHAHE (config-if)#exit
SHAHE (config)#ip host BDL 192.168.0.1 192.168.15.2
Router2
Router>enable
Router#configure terminal
Router(config)#hostname BDL
BDL(config)#enable password cisco
BDL (config)#enable secret class
BDL (config)#line console 0
BDL (config-line)#password cisco
BDL (config-line)#login
BDL (config-line)#line vty 0 4
BDL (config-line)#password cisco
BDL (config-line)#login
BDL (config-line)#exit
BDL (config)#interface serial 0/0
BDL (config-if)#ip address 192.168.15.2 255.255.255.252
BDL (config-if)#no shutdown
BDL (config-if)#exit
BDL (config)#interface fastEthernet 0/0
BDL (config-if)#ip address 192.168.0.1 255.255.255.0
BDL (config-if)#no shutdown
BDL (config-if)#exit
BDL (config)#ip host BERLIN 192.168.1.129 192.168.15.1
Step 2 保存路由器上的配置文件
SHAHE#copy running-config startup-config
Destination filename [startup-config]? [Enter]
BDL#copy running-config startup-config
Destination filename [startup-config]? [Enter]
Step 3 为PC配置正确的IP地址，子网掩码和缺省网关
连接到八达岭的PC
IP Address: 192.168.0.2
Subnet mask: 255.255.255.0
Default gateway: 192.168.0.1
连接到沙河的PC
IP Address: 192.168.1.130 (can’t use 128 address of subnet)
Subnet mask: 255.255.255.128
Default gateway: 192.168.1.129
Step 4 在路由器沙河上启动OSPF
SHAHE(config)#router ospf 1
SHAHE (config-router)#network 192.168.1.128 0.0.0.63 area 0
SHAHE (config-router)#network 192.168.15.0 0.0.0.3 area 0
SHAHE (config-router)#end
Step 5 在路由器八达岭上启动OSPF
BDL(config)#router ospf 1
BDL (config-router)#network 192.168.0.0 0.0.0.255 area 0
BDL (config-router)#network 192.168.15.0 0.0.0.3 area 0
BDL (config-router)#end
