9.4实验4：帧中继环境下点到多点模式.doc

1.实验目的（1）帧中继子接口下静态映射（2）点到多点模式的特征（3）点到多点模式下 OSPF 的配置和调试2.拓扑结构实验拓扑如图 9-3 所示。图 9-3 帧中继环境下点到多点模式3.实验步骤（1）步骤 1：配置路由器 R1R1(config)#interface Serial0/0/0 R1(config-if)#no ip address R1(config-if)#encapsulation frame-relay R1(config-if)#no frame-relay inverse-arp R1(config-if)#no shutdown R1(config)#interface Serial0/0/0.1 multipoint R1(config-subif)#ip address 134.1.1.1 255.255.255.0 R1(config-subif)#ip ospf network point-to-multipoint R1(config-subif)#frame-relay map ip 134.1.1.3 103 broadcast R1(config-subif)#frame-relay map ip 134.1.1.4 104 broadcast R1(config-subif)#no frame-relay inverse-arpR1(config)#router ospf 1 R1(config-router)#router-id 1.1.1.1 R1(config-router)#network 1.1.1.0 0.0.0.255 area 0 R1(config-router)#network 134.1.1.0 0.0.0.255 area 0 （2）步骤 2：配置路由器 R3R3(config)#interface Serial0/0/1 R3(config-if)#ip address 134.1.1.3 255.255.255.0 R3(config-if)#encapsulation frame-relay R3(config-if)#ip ospf network point-to-multipoint R3(config-if)#frame-relay map ip 134.1.1.1 301 broadcast R3(config-if)#no frame-relay inverse-arp R3(config-if)#no shutdown R3(config)#router ospf 1 R3(config-router)#router-id 3.3.3.3 R3(config-router)#network 3.3.3.0 0.0.0.255 area 0 R3(config-router)#network 134.1.1.0 0.0.0.255 area 0 （3）步骤 3：配置路由器 R4R3(config)#interface Serial0/0/1 R3(config-if)#ip address 134.1.1.4 255.255.255.0 R3(config-if)#encapsulation frame-relay R3(config-if)#ip ospf network point-to-multipoint R3(config-if)#frame-relay map ip 134.1.1.1 401 broadcast R3(config-if)#no frame-relay inverse-arp R3(config-if)#no shutdown R3(config)#router ospf 1 R3(config-router)#router-id 4.4.4.4 R3(config-router)#network 4.4.4.0 0.0.0.255 area 0 R3(config-router)#network 134.1.1.0 0.0.0.255 area 0 4.实验调试（1）show ip ospf interfaceR1#show ip ospf interface s0/0/0.1Serial0/0/0.1 is up, line protocol is upInternet Address 134.1.1.1/24, Area 0Process ID 1, Router ID 1.1.1.1, Network Type POINT_TO_MULTIPOINT, Cost: 64 Transmit Delay is 1 sec, State POINT_TO_MULTIPOINT,Timer intervals configured, Hello 30, Dead 120, Wait 120, Retransmit 5/ POINT_TO_MULTIPOINT 模式下，Hello 周期为 30 秒oob-resync timeout 120Hello due in 00:00:00Index 2/2, flood queue length 0Next 00(0)/00(0)Last flood scan length is 1, maximum is 1Last flood scan time is 0 msec, maximum is 0 msecNeighbor Count is 2, Adjacent neighbor count is 2Adjacent with neighbor 4.4.4.4Adjacent with neighbor 3.3.3.3Suppress hello for 0 neighbor(s)（2）show ip route R1#show ip route ospf3.0.0.0/32 is subnetted, 1 subnetsO 3.3.3.3 110/65 via 134.1.1.3, 00:02:11, Serial0/0/0.1 4.0.0.0/32 is subnetted, 1 subnetsO 4.4.4.4 110/65 via 134.1.1.4, 00:02:11, Serial0/0/0.1 134.1.0.0/16 is variably subnetted, 3 subnets, 2 masksO 134.1.1.4/32 110/64 via 134.1.1.4, 00:02:11, Serial0/0/0.1O 134.1.1.3/32 110/64 via 134.1.1.3, 00:02:11, Serial0/0/0.1R3#show ip route ospf1.0.0.0/32 is subnetted, 1 subnetsO 1.1.1.1 110/65 via 134.1.1.1, 00:03:41, Serial0/0/14.0.0.0/32 is subnetted, 1 subnetsO 4.4.4.4 110/129 via 134.1.1.1, 00:03:41, Serial0/0/1134.1.0.0/16 is variably subnetted, 3 subnets, 2 masksO 134.1.1.4/32 110/128 via 134.1.1.1, 00:03:41, Serial0/0/1O 134.1.1.1/32 110/64 via 134.1.1.1, 00:03:41, Serial0/0/1以上输出表明
