任務1：實驗步驟

步驟1：設備的基本配置

配置PC1：VPCS> set pcname PC1 //設置主機名PC1> ip 192.168.1.1/24 192.168.1.254 //設置IP地址與網關

配置PC2：VPCS> set pcname PC2PC2> ip 192.168.2.1/24 192.168.2.254

配置R1： Router>enableRouter#configure terminalRouter(config)#hostname R1R1(config)#no ip domain-lookupR1(config)#line console 0R1(config-line)#exec-timeout 0 0R1(config-line)#logging synchronousR1(config-line)#exitR1(config)#interface ethernet0/0R1(config-if)#ip address 192.168.1.254 255.255.255.0R1(config-if)#no shutdownR1(config-if)#exitR1(config)#interface serial1/0R1(config-if)#ip address 192.168.12.1 255.255.255.0R1(config-if)#no shutdownR1(config-if)#endR1#

配置R2： Router>enableRouter#configure terminalRouter(config)#hostname R2R2(config)#no ip domain-lookupR2(config)#line console 0R2(config-line)#exec-timeout 0 0R2(config-line)#logging synchronousR2(config-line)#exitR2(config)#interface serial1/0R2(config-if)#ip address 192.168.12.2 255.255.255.0R2(config-if)#no shutdownR2(config-if)#exitR2(config)#interface serial1/1R2(config-if)#ip address 192.168.23.2 255.255.255.0R2(config-if)#no shutdownR2(config-if)#endR2#

步驟2：檢查設備接口狀態

檢查PC1：

PC1> show ipNAME : PC1[1]IP/MASK : 192.168.1.1/24GATEWAY : 192.168.1.254DNS :MAC : 00:50:79:66:68:04LPORT : 20000RHOST:PORT : 127.0.0.1:30000MTU : 1500

檢查R1：

R1#show ip interface briefInterface IP-Address OK? Method Status ProtocolEthernet0/0 192.168.1.254 YES manual up up Ethernet0/1 unassigned YES unset administratively down down Ethernet0/2 unassigned YES unset administratively down down Ethernet0/3 unassigned YES unset administratively down down Serial1/0 192.168.12.1 YES manual up up Serial1/1 unassigned YES unset administratively down down Serial1/2 unassigned YES unset administratively down down Serial1/3 unassigned YES unset administratively down down

檢查R2：

R2#show ip interface briefInterface IP-Address OK?

檢查R3：

R3#show ip interface briefInterface IP-Address OK?

檢查PC2：

PC2> show ipNAME : PC2[1]IP/MASK : 192.168.2.1/24GATEWAY : 192.168.2.254DNS :MAC : 00:50:79:66:68:05LPORT : 20000RHOST:PORT : 127.0.0.1:30000MTU : 1500

步驟3：測試直連網絡的連通性

測試PC1跟網關的網絡連通性：

PC1> ping 192.168.1.25484 bytes from 192.168.1.254 icmp_seq=1 ttl=255 time=0.359 ms84 bytes from 192.168.1.254 icmp_seq=2 ttl=255 time=0.459 ms84 bytes from 192.168.1.254 icmp_seq=3 ttl=255 time=0.463 ms84 bytes from 192.168.1.254 icmp_seq=4 ttl=255 time=0.403 ms84 bytes from 192.168.1.254 icmp_seq=5 ttl=255 time=0.417 ms

測試R1跟R2之間的網絡連通性：

R1#ping 192.168.12.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 8/9/10 ms

測試R2跟R3之間的網絡連通性：

R2#ping 192.168.23.3Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.23.3, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 9/9/11 ms

測試PC2跟網關的網絡連通性：

PC2> ping 192.168.2.25484 bytes from 192.168.2.254 icmp_seq=1 ttl=255 time=0.469 ms84 bytes from 192.168.2.254 icmp_seq=2 ttl=255 time=0.484 ms84 bytes from 192.168.2.254 icmp_seq=3 ttl=255 time=0.518 ms84 bytes from 192.168.2.254 icmp_seq=4 ttl=255 time=0.400 ms84 bytes from 192.168.2.254 icmp_seq=5 ttl=255 time=0.405 ms注意，雖然設備之間的網絡連通性正常了，但是PC1和PC2之間的網絡是不可達的：PC1> ping 192.168.2.1*192.168.1.254 icmp_seq=1 ttl=255 time=0.345 ms (ICMP type:3, code:1, Destination host unreachable)*192.168.1.254 icmp_seq=2 ttl=255 time=0.462 ms (ICMP type:3, code:1, Destination host unreachable)*192.168.1.254 icmp_seq=3 ttl=255 time=0.543 ms (ICMP type:3, code:1, Destination host unreachable)*192.168.1.254 icmp_seq=4 ttl=255 time=0.494 ms (ICMP type:3, code:1, Destination host unreachable)*192.168.1.254 icmp_seq=5 ttl=255 time=0.467 ms (ICMP type:3, code:1, Destination host unreachable)因為PC1把數據包發送給R1后，R1沒有到達網絡192.168.2.0/24的路由，所以R1無法轉發數據包。

檢查R1的路由表：

步驟4：配置靜態路由

配置R1：

R1(config)#ip route 192.168.2.0 255.255.255.0 192.168.12.2//當然也可以跟出接口路由要有去有回網絡才能通，所以R3上要配置回程路由。

配置R3：

R3(config)#ip route 192.168.1.0 255.255.255.0 serial 1/0//當然也可以跟下一跳另外，沿途的路由器也要有去往源和目標網絡的路由。

配置R2：

R2(config)#ip route 192.168.1.0 255.255.255.0 192.168.12.1//當然也可以跟出接口R2(config)#ip route 192.168.2.0 255.255.255.0 192.168.23.3//當然也可以跟出接口這樣當PC1把數據包發送給R1時，R1查路由表：R1#show ip routeCodes: L - local, 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 route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfRGateway of last resort is not set 192.168.1.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.1.0/24 is directly connected, Ethernet0/0L 192.168.1.254/32 is directly connected, Ethernet0/0S 192.168.2.0/24 [1/0] via 192.168.12.2 192.168.12.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.12.0/24 is directly connected, Serial1/0L 192.168.12.1/32 is directly connected, Serial1/0R1有到達網絡192.168.2.0/24的路由，所以R1把數據包發送給下一跳R2，R2檢查路由表：R2#show ip routeCodes: L - local, 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 route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfRGateway of last resort is not setS 192.168.1.0/24 [1/0] via 192.168.12.1S 192.168.2.0/24 [1/0] via 192.168.23.3 192.168.12.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.12.0/24 is directly connected, Serial1/0L 192.168.12.2/32 is directly connected, Serial1/0 192.168.23.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.23.0/24 is directly connected, Serial1/1L 192.168.23.2/32 is directly connected, Serial1/1R2有到達網絡192.168.2.0/24的路由，所以R2把數據包發送給下一跳R3，R3檢查路由表：R3#show ip routeCodes: L - local, 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 route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfRGateway of last resort is not setS 192.168.1.0/24 is directly connected, Serial1/0 192.168.2.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.2.0/24 is directly connected, Ethernet0/0L 192.168.2.254/32 is directly connected, Ethernet0/0 192.168.23.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.23.0/24 is directly connected, Serial1/0L 192.168.23.3/32 is directly connected, Serial1/0R3上192.168.2.0/24是自己的直連網絡，所以R3把數據包直接發給PC2?；爻虜祿霓D發原理一樣，這里不再撰述。

步驟5：測試PC1跟PC2的網絡連通性

PC1> ping 192.168.2.184 bytes from 192.168.2.1 icmp_seq=1 ttl=61 time=22.503 ms84 bytes from 192.168.2.1 icmp_seq=2 ttl=61 time=18.859 ms84 bytes from 192.168.2.1 icmp_seq=3 ttl=61 time=19.251 ms84 bytes from 192.168.2.1 icmp_seq=4 ttl=61 time=19.350 ms84 bytes from 192.168.2.1 icmp_seq=5 ttl=61 time=17.856 ms因為需求要求全網路由可達；如果這個時候在R1上Ping PC2，能不能通呢？不能！在R1上Ping PC2，數據包源地址是192.168.12.1，數據包能到達PC2，但是回不來，因為R3上沒有到達192.168.12.0/24的路由；同理，R3上Ping PC1也不通，因為R1沒有到達192.168.23.0/24的路由。

檢查R3的路由表：

R3#show ip routeCodes: L - local, 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 route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfRGateway of last resort is not setS 192.168.1.0/24 is directly connected, Serial1/0 192.168.2.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.2.0/24 is directly connected, Ethernet0/0L 192.168.2.254/32 is directly connected, Ethernet0/0 192.168.23.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.23.0/24 is directly connected, Serial1/0L 192.168.23.3/32 is directly connected, Serial1/0R3沒有到達網絡192.168.12.0/24的路由。

配置R3：

R3(config)#ip route 192.168.12.0 255.255.255.0 192.168.23.2//當然也可以跟出接口

同理，配置R1：

R1(config)#ip route 192.168.23.0 255.255.255.0 serial 1/0//當然也可以跟下一跳

檢查R1的路由表：

檢查R3的路由表：

R3#show ip routeCodes: L - local, 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 route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfRGateway of last resort is not setS 192.168.1.0/24 is directly connected, Serial1/0 192.168.2.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.2.0/24 is directly connected, Ethernet0/0L 192.168.2.254/32 is directly connected, Ethernet0/0S 192.168.12.0/24 [1/0] via 192.168.23.2 192.168.23.0/24 is variably subnetted, 2 subnets, 2 masksC 192.168.23.0/24 is directly connected, Serial1/0L 192.168.23.3/32 is directly connected, Serial1/0R3有到達192.168.1.0/24和192.168.12.0/24的路由。

步驟6：測試網絡連通性

在PC1上測試：

PC1> ping 192.168.2.184 bytes from 192.168.2.1 icmp_seq=1 ttl=61 time=21.429 ms84 bytes from 192.168.2.1 icmp_seq=2 ttl=61 time=18.079 ms84 bytes from 192.168.2.1 icmp_seq=3 ttl=61 time=19.108 ms84 bytes from 192.168.2.1 icmp_seq=4 ttl=61 time=19.006 ms84 bytes from 192.168.2.1 icmp_seq=5 ttl=61 time=18.163 msPC1> ping 192.168.23.384 bytes from 192.168.23.3 icmp_seq=1 ttl=253 time=18.265 ms84 bytes from 192.168.23.3 icmp_seq=2 ttl=253 time=18.186 ms84 bytes from 192.168.23.3 icmp_seq=3 ttl=253 time=18.184 ms84 bytes from 192.168.23.3 icmp_seq=4 ttl=253 time=18.257 ms84 bytes from 192.168.23.3 icmp_seq=5 ttl=253 time=18.240 msPC1> ping 192.168.12.284 bytes from 192.168.12.2 icmp_seq=1 ttl=254 time=9.899 ms84 bytes from 192.168.12.2 icmp_seq=2 ttl=254 time=9.380 ms84 bytes from 192.168.12.2 icmp_seq=3 ttl=254 time=9.159 ms84 bytes from 192.168.12.2 icmp_seq=4 ttl=254 time=9.300 ms84 bytes from 192.168.12.2 icmp_seq=5 ttl=254 time=9.268 ms

任務2：實驗拓撲?

任務2：實驗需求

1.?在R1和R3上刪除任務1的靜態路由；

2.?在路由器R1、R3上配置默認路由，使得全網路由可達。

任務2：實驗步驟

步驟1：刪除R1和R3上的靜態路由并配置默認路由

配置R1：

R1(config)#no ip route 192.168.2.0 255.255.255.0 192.168.12.2R1(config)#no ip route 192.168.23.0 255.255.255.0 Serial1/0R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2

配置R3：
