CCNP(BSCI)实验：配置EIGRP帧中继Hub and Spoke物理接口

第三步：R3上的配置R3(config-if)#ip add 3.3.3.3 255.255.255.0R3(config-if)#int s3/0R3(config-if)#ip add 123.1.1.3 255.255.255.0R3(config-if)#en frR3(config-if)#no fr R3(config-if)#no fr invR3(config-if)#fr map ip 123.1.1.1 301 bR3(config-if)#fr map ip 123.1.1.2 301 b实验过程：第一步：在R1上运行eigrpR1(config)#router eigrp 11R1(config-router)#net 1.1.1.1R1(config-router)#net 123.1.1.1R1(config-router)#exitR1(config)#exit第二步：在R2上运行eigrpR2(config)#router ei 11R2(config-router)#net 2.2.2.2R2(config-router)#net 123.1.1.2R2(config-router)#end第三步：在R3上运行eigrpR3(config)#router ei 11R3(config-router)#net 3.3.3.3R3(config-router)#net 123.1.1.3R3(config-router)#end第四步：查看路由表R1#sh ip rou…………1.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 1.1.1.0/24 is directly connected, Loopback0D 1.0.0.0/8 is a summary, 00:32:40, Null0D 2.0.0.0/8 [90/2297856] via 123.1.1.2, 00:31:48, Serial3/0D 3.0.0.0/8 [90/2297856] via 123.1.1.3, 00:30:57, Serial3/0123.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 123.1.1.0/24 is directly connected, Serial3/0D 123.0.0.0/8 is a summary, 00:32:40, Null0

R2#sh ip rou……………………D 1.0.0.0/8 [90/2297856] via 123.1.1.1, 00:32:44, Serial3/02.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 2.2.2.0/24 is directly connected, Loopback0D 2.0.0.0/8 is a summary, 00:33:14, Null0123.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 123.1.1.0/24 is directly connected, Serial3/0D 123.0.0.0/8 is a summary, 00:33:14, Null0//这里没有去R3的回环接口1.1.1.1的路由

R3#sh ip rou………………

D 1.0.0.0/8 [90/2297856] via 123.1.1.1, 00:32:21, Serial3/03.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 3.3.3.0/24 is directly connected, Loopback0D 3.0.0.0/8 is a summary, 00:33:06, Null0123.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 123.1.1.0/24 is directly connected, Serial3/0D 123.0.0.0/8 is a summary, 00:33:06, Null0//这里没有去R2回环接口2.2.2.2的路由第五步：在R1的S3/0接口下关闭水平分割R1(config-if)#int s3/0R1(config-subif)#no ip sp ei 11//非常重要的一句，ospf则不需要第五步：小小测试R2#ping 3.3.3.3 so 2.2.2.2

Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:Packet sent with a source address of 2.2.2.2 !!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 12/42/88 msR2#
