熟悉CISCO IOS的基本配置

CISCO IOS常用配置命令

Router>enable

Router#configure terminal

Router(config)#enable secret xmws   //设置enable的密码为xmws

Router(config)#enable password wisdom   //设置enable的密码为wisdom,不能和enable secret 设置的密码相同,如果都设置,secret生效

Router(config)#no ip domain-lookup   //关掉域名查找功能

Router(config)#service password-encryption   //对明文口令进行加密,比如加密Console口、VTY或enable password设置的密码,这样密码不再显示为明文

Router(config)#line console 0   //进入Cconsole口

Router(config-line)#password xmws  //设置Console口密码为xmws

Router(config-line)#login  //启用密码

Router(config-line)#exec-timeout 0 0  //设置操作会话不超时

Router(config-line)#logging synchronous  //配置光标跟随, 阻止控制台信息打断你当前的输入,从而使输入信息显得更为简单易读

Router(config)#line vty 0 4  //进入VTY

Router(config-line)#password cisco

Router(config-line)#login

Router(config-line)#exec-timeout 0 0

Router(config-line)#logging synchronous

注:VTY (虚拟终端) 在网络操作系统(包括Cisco IOS)中是一个接受telent或ssh连接的逻辑端口。

PC1(config-if)#no shutdown   //激活接口

PC1(config-if)#exit

PC1(config)#ip default-gateway 192.168.10.254   //配置默认网关

PC1(config)#end

PC1#show ip interface brief   //查看接口IP地址和状态

Interface                  IP-Address      OK? Method Status                Protocol

步骤3:测试直连网络的连通性

测试PC1跟网关的网络连通性:

PC1> ping 192.168.1.254

84 bytes from 192.168.1.254 icmp_seq=1 ttl=255 time=0.359 ms

84 bytes from 192.168.1.254 icmp_seq=2 ttl=255 time=0.459 ms

84 bytes from 192.168.1.254 icmp_seq=5 ttl=255 time=0.417 ms

测试R1跟R2之间的网络连通性:

R1#ping 192.168.12.2

Type 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

测试R2跟R3之间的网络连通性:

R2#ping 192.168.23.3

Type 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

测试PC2跟网关的网络连通性:

PC2> ping 192.168.2.254

84 bytes from 192.168.2.254 icmp_seq=1 ttl=255 time=0.469 ms

84 bytes from 192.168.2.254 icmp_seq=2 ttl=255 time=0.484 ms

84 bytes from 192.168.2.254 icmp_seq=3 ttl=255 time=0.518 ms

84 bytes from 192.168.2.254 icmp_seq=4 ttl=255 time=0.400 ms

84 bytes from 192.168.2.254 icmp_seq=5 ttl=255 time=0.405 ms

注意,虽然设备之间的网络连通性正常了,但是PC1和PC2之间的网络是不可达的:

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)

因为PC1把数据包发送给R1后,R1没有到达网络192.168.2.0/24的路由,所以R1无法转发数据包。

检查R1的路由表:

R1#show ip route

Codes: 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 PfR

Gateway of last resort is not set

      192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.1.0/24 is directly connected, Ethernet0/0

L        192.168.1.254/32 is directly connected, Ethernet0/0

      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.12.0/24 is directly connected, Serial1/0

L        192.168.12.1/32 is directly connected, Serial1/0

R1只有两条直连路由,分别是192.168.1.0/24和192.168.12.0/24。

因此,我们需要在R1上配置去往192.168.2.0/24的静态路由。

步骤4:配置静态路由

配置R1

R1(config)#ip route 192.168.2.0 255.255.255.0 192.168.12.2

//当然也可以跟出接口

路由要有去有回网络才能通,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

//当然也可以跟下一跳

另外,沿途的路由器也要有去往源和目标网络的路由。

配置R2

R2(config)#ip route 192.168.1.0 255.255.255.0 192.168.12.1

//当然也可以跟出接口

R2(config)#ip route 192.168.2.0 255.255.255.0 192.168.23.3

//当然也可以跟出接口

这样当PC1把数据包发送给R1时,R1查路由表:

R1#show ip route

Codes: 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 PfR

Gateway of last resort is not set

      192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.1.0/24 is directly connected, Ethernet0/0

L        192.168.1.254/32 is directly connected, Ethernet0/0

S     192.168.2.0/24 [1/0] via 192.168.12.2

      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.12.0/24 is directly connected, Serial1/0

L        192.168.12.1/32 is directly connected, Serial1/0

R1有到达网络192.168.2.0/24的路由,所以R1把数据包发送给下一跳R2,R2检查路由表:

R2#show ip route

Codes: 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 PfR

Gateway of last resort is not set

S     192.168.1.0/24 [1/0] via 192.168.12.1

S     192.168.2.0/24 [1/0] via 192.168.23.3

      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.12.0/24 is directly connected, Serial1/0

L        192.168.12.2/32 is directly connected, Serial1/0

      192.168.23.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.23.0/24 is directly connected, Serial1/1

L        192.168.23.2/32 is directly connected, Serial1/1

R2有到达网络192.168.2.0/24的路由,所以R2把数据包发送给下一跳R3,R3检查路由表:

R3#show ip route

Codes: 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 PfR

Gateway of last resort is not set

S     192.168.1.0/24 is directly connected, Serial1/0

      192.168.2.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.2.0/24 is directly connected, Ethernet0/0

L        192.168.2.254/32 is directly connected, Ethernet0/0

      192.168.23.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.23.0/24 is directly connected, Serial1/0

L        192.168.23.3/32 is directly connected, Serial1/0

R3上192.168.2.0/24是自己的直连网络,所以R3把数据包直接发给PC2。

回程数据包的转发原理一样,这里不再撰述。

步骤5:测试PC1跟PC2的网络连通性

PC1> ping 192.168.2.1

84 bytes from 192.168.2.1 icmp_seq=1 ttl=61 time=22.503 ms

84 bytes from 192.168.2.1 icmp_seq=2 ttl=61 time=18.859 ms

84 bytes from 192.168.2.1 icmp_seq=3 ttl=61 time=19.251 ms

84 bytes from 192.168.2.1 icmp_seq=4 ttl=61 time=19.350 ms

84 bytes from 192.168.2.1 icmp_seq=5 ttl=61 time=17.856 ms

因为需求要求全网路由可达;

如果这个时候在R1上Ping PC2,能不能通呢?不能!

在R1上Ping PC2,数据包源地址是192.168.12.1,数据包能到达PC2,但是回不来,因为R3上没有到达192.168.12.0/24的路由;

同理,R3上Ping PC1也不通,因为R1没有到达192.168.23.0/24的路由。

检查R3的路由表:

R3#show ip route

Codes: 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

       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 PfR

Gateway of last resort is not set

D     172.16.0.0/16 [90/2297856] via 192.168.23.3, 00:02:53, Serial1/1

                    [90/2297856] via 192.168.12.1, 00:02:53, Serial1/0

D     192.168.1.0/24 [90/2195456] via 192.168.12.1, 00:19:55, Serial1/0

D     192.168.2.0/24 [90/2195456] via 192.168.23.3, 00:18:53, Serial1/1

      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.12.0/24 is directly connected, Serial1/0

L        192.168.12.2/32 is directly connected, Serial1/0

      192.168.23.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.23.0/24 is directly connected, Serial1/1

L        192.168.23.2/32 is directly connected, Serial1/1

R2的路由表去往172.16.0.0/16是等价负载的,为什么?

EIGRP在自动汇总打开的情况下,在主类网络边界会执行自动汇总,将路由汇总成主类网络;

R1和R3的Lo1、Lo2、Lo3接口地址都是B类地址,所以R1和R3把它们汇总了B类网络,即,172.16.0.0/16。

假设这个时候R2有数据包要去往172.16.1.0/24或其它网络,那么有可能会出现以下情况:

R2#ping 172.16.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:

U.U.U

Success rate is 0 percent (0/5)

R2#ping 172.16.2.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.16.2.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 7/9/11 ms

因为路由是负载的,所以有可能有的网络通,有的网络不通。

怎么解决?关闭自动汇总!

步骤6:关闭EIGRP自动汇总

注意,12.X版本的IOS自动汇总默认打开,15.X版本的IOS自动汇总默认关闭。

配置R1

R1(config)#router eigrp 100

R1(config-router)#no auto-summary

R1(config-router)#end

R1#

配置R2

R2(config)#router eigrp 100

R2(config-router)#no auto-summary

R2(config-router)#end

R2#

配置R3

R3(config)#router eigrp 100

R3(config-router)#no auto-summary

R3(config-router)#end

R3#

关闭自动汇总之后,R2的路由表看到的就是Loopback口的明细路由而不是汇总路由了。

检查R2

R2#show ip route

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

R1(config-router)#router-id 1.1.1.1

R1(config-router)#network 192.168.1.0 0.0.0.255 area 0

R1(config-router)#network 192.168.12.0 0.0.0.255 area 0

R1(config-router)#end

R1#

配置R2

R2(config)#router ospf 1

R2(config-router)#router-id 2.2.2.2

R3(config-router)#network 192.168.23.0 0.0.0.255 area 1

R3(config-router)#network 192.168.2.0 0.0.0.255 area 1

R3(config-router)#end

R3#

实验检查

步骤1:检查OSPF邻居

检查R1

R1#show ip ospf neighbor

Neighbor ID     Pri   State           Dead Time   Address         Interface

2.2.2.2           0   FULL/  -        00:00:31    192.168.12.2    Serial1/0

Full是完全邻接状态,是正常的状态。

检查R2

R2#show ip ospf neighbor

Neighbor ID     Pri   State           Dead Time   Address         Interface

1.1.1.1           0   FULL/  -        00:00:31    192.168.12.1    Serial1/0

3.3.3.3           0   FULL/  -        00:00:39    192.168.23.3    Serial1/1

检查R3

R3#show ip ospf neighbor

Neighbor ID     Pri   State           Dead Time   Address         Interface

        1.           0   FULL/  -        00:00:33    192.168.23.2    Serial1/0

步骤2:检查OSPF路由

检查R1

R1#show ip route

Codes: 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 PfR

Gateway of last resort is not set

      1.0.0.0/32 is subnetted, 1 subnets

C        1.1.1.1 is directly connected, Loopback0

      192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.1.0/24 is directly connected, Ethernet0/0

L        192.168.1.254/32 is directly connected, Ethernet0/0

O IA  192.168.2.0/24 [110/138] via 192.168.12.2, 00:04:48, Serial1/0

      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.12.0/24 is directly connected, Serial1/0

L        192.168.12.1/32 is directly connected, Serial1/0

O IA  192.168.23.0/24 [110/128] via 192.168.12.2, 00:06:10, Serial1/0

R1有两条O IA的路由,O IA表示OSPF区域间的路由;

因为R1所有接口都是属于Area 0,192.168.2.0/24和192.168.23.0/24都是属于Area 1,所以通过R2跨区域传递给R1之后,就形成了O IA路由。

检查R2

R2#show ip route

Codes: 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 PfR

Gateway of last resort is not set

      2.0.0.0/32 is subnetted, 1 subnets

C        2.2.2.2 is directly connected, Loopback0

O     192.168.1.0/24 [110/74] via 192.168.12.1, 00:09:55, Serial1/0

O     192.168.2.0/24 [110/74] via 192.168.23.3, 00:08:24, Serial1/1

      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.12.0/24 is directly connected, Serial1/0

L        192.168.12.2/32 is directly connected, Serial1/0

      192.168.23.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.23.0/24 is directly connected, Serial1/1

L        192.168.23.2/32 is directly connected, Serial1/1

因为R1既有接口属于Area 0,也有接口属于Area 1;

所以R1的路由表看到的都是O路由,O表示OSPF区域内的路由。
