LAB.10动态路由协议――单域OSPF配置.doc

LAB.10动态路由协议-单域OSPF配置实验目的:1. 理解动态路由协议OSPF的内容； 2. 理解OSPF等链路状态协议的算法处理过程； 3. 掌握OSPF的基本配置，并与距离失量协议的配置过程相比较； 4. 掌握DR和BDR，手动配置DR、BDR。 实验拓扑如下实验过程：R1配置如下：R1(config)#interface Loopback0R1(config-if)#ip address 1.1.1.1 255.255.255.255R1(config-if)#interface FastEthernet0/0R1(config-if)#ip address 172.16.13.1 255.255.255.0R1(config-if)#interface Serial1/0R1(config-if)#ip address 172.16.12.1 255.255.255.0R1(config-if)#clock rate 64000R1(config)#router ospf 110OSPF路由配置模式，进程号为110R1(config-router)#router-id 1.1.1.1定义路由器IDR1(config-router)#network 1.1.1.1 0.0.0.0 area 0向全网通告1.1.1.1，并定义这个地址在区域0内R1(config-router)#network 172.16.12.0 0.0.0.255 area 0向全网通告172.16.12.0这个网段，并定义这个网段在区域0内R1(config-router)#network 172.16.13.0 0.0.0.255 area 0R2配置如下：R2(config)#interface Loopback0R2(config-if)#ip address 2.2.2.2 255.255.255.255R2(config-if)#interface Serial1/0R2(config-if)#ip address 172.16.12.2 255.255.255.0R2(config-if)#clock rate 64000R2(config-if)#interface Serial1/1R2(config-if)#ip address 172.16.23.2 255.255.255.0R2(config-if)#clock rate 64000R2(config)router ospf 110R2(config-router)#router-id 2.2.2.2R2(config-router)#network 2.2.2.2 0.0.0.0 area 0R2(config-router)#network 172.16.12.0 0.0.0.255 area 0R2(config-router)#network 172.16.23.0 0.0.0.255 area 0R3配置如下：R3(config)#interface Loopback0进入接口配置模式，配置一个环回口R3(config-if)#ip address 3.3.3.3 255.255.255.255R3(config-if)#interface FastEthernet0/0R3(config-if)#ip address 172.16.13.2 255.255.255.0R3(config-if)#interface Serial1/1R3(config-if)#ip address 172.16.23.1 255.255.255.0R3(config-if)#clock rate 64000R3(config)#router ospf 110R3(config-router)#router-id 3.3.3.3R3(config-router)#network 3.3.3.3 0.0.0.0 area 0R3(config-router)#network 172.16.13.0 0.0.0.255 area 0R3(config-router)#network 172.16.23.0 0.0.0.255 area 0查看R1、R2、R3路由表R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static routeGateway of last resort is not set 1.0.0.0/32 is subnetted, 1 subnetsC 1.1.1.1 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnetsO 2.2.2.2 110/65 via 172.16.12.2, 00:05:53, Serial1/0 3.0.0.0/32 is subnetted, 1 subnetsO代表OSPF的路由表项，从本地端口Serial1/0学到的目标网络为2.2.2.2的路由，建立邻居时间为05：53O 3.3.3.3 110/2 via 172.16.13.2, 00:05:53, FastEthernet0/0 172.16.0.0/24 is subnetted, 3 subnetsO 172.16.23.0 110/65 via 172.16.13.2, 00:05:53, FastEthernet0/0C 172.16.12.0 is directly connected, Serial1/0C 172.16.13.0 is directly connected, FastEthernet0/0R2#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static routeGateway of last resort is not set 1.0.0.0/32 is subnetted, 1 subnetsO 1.1.1.1 110/65 via 172.16.12.1, 00:06:12, Serial1/0 2.0.0.0/32 is subnetted, 1 subnetsC 2.2.2.2 is directly connected, Loopback0 3.0.0.0/32 is subnetted, 1 subnetsO 3.3.3.3 110/65 via 172.16.23.1, 00:06:12, Serial1/1 172.16.0.0/24 is subnetted, 3 subnetsC 172.16.23.0 is directly connected, Serial1/1C 172.16.12.0 is directly connected, Serial1/0O 172.16.13.0 110/65 via 172.16.12.1, 00:06:12, Serial1/0 110/65 via 172.16.23.1, 00:06:12, Serial1/1R3#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static routeGateway of last resort is not set 1.0.0.0/32 is subnetted, 1 subnetsO 1.1.1.1 110/2 via 172.16.13.1, 00:06:33, FastEthernet0/0 2.0.0.0/32 is subnetted, 1 subnetsO 2.2.2.2 110/65 via 172.16.23.2, 00:06:33, Serial1/1 3.0.0.0/32 is subnetted, 1 subnetsC 3.3.3.3 is directly connected, Loopback0 172.16.0.0/24 is subnetted, 3 subnetsC 172.16.23.0 is directly connected, Serial1/1O 172.16.12.0 110/65 via 172.16.13.1, 00:06:33, FastEthernet0/0C 172.16.13.0 is directly connected, FastEthernet0/0在R1、R2查看DR、BDRR1#show ip ospf neighbor查看OSPF的邻居 Neighbor ID Pri State Dead Time Address Interface2.2.2.2 0 FULL/ - 00:00:3
