从R2上验证和R1 R3的连通性

R2#ping 192.168.12.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.12.1, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 20/32/56 ms

R2#ping 192.168.23.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.23.2, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 20/32/44 ms

但是lo 口是不通的

R1#ping 3.3.3.3 sour

R1#ping 3.3.3.3 source lo 0

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 1.1.1.1

.....

Success rate is 0 percent (0/5)

开始配置路由协议

R1#

R1#conf t

Enter configuration commands, one per line. End with CNTL/Z.

R1(config)#router ospf 100

R1(config-router)#router-id 1.1.1.1

R1(config-router)#network 1.1.1.1 0.0.0.0 area 0

R1(config-router)#network 192.168.12.1 0.0.0.0 area 0

R1(config-router)#end

R1#

*Mar 1 01:01:21.491: %SYS-5-CONFIG_I: Configured from console by console

R2#conf t

Enter configuration commands, one per line. End with CNTL/Z.

R2(config)#router ospf 100

R2(config-router)#router-id 2.2.2.2

R2(config-router)#network 192.168.12.2 0.0.0.0 area 0

R2(config-router)#network 2.2.2.2 0.0.0.0 a 0

R2(config-router)#network 192.168.23.1 0.0.0.0 a 1

R3(config)#router ospf 100

R3(config-router)#router-id 3.3.3.3

R3(config-router)#network 192.168.23.2 0.0.0.0 a 1

R3(config-router)#network

*Mar 1 01:07:21.891: %OSPF-5-ADJCHG: Process 100, Nbr 2.2.2.2 on FastEthernet1/0 from LOADING to FULL, Loading Done

R3(config-router)#network 3.3.3.3 0.0.0.0 a 1

已经可以看到进程为100的 邻居为2.2.2.2 状态已经起来了

看下R1

R1#sh ip ospf neighbor

Neighbor ID Pri State Dead Time Address Interface

2.2.2.2 1 FULL/BDR 00:00:37 192.168.12.2 FastEthernet0/0

R1#

邻居关系已经建立,状态是2.2.2.2是BDR备用选举路由器

在R2上看,R1是主选举主

R2#sh ip ospf neighbor

Neighbor ID Pri State Dead Time Address Interface

1.1.1.1 1 FULL/DR 00:00:37 192.168.12.1 FastEthernet0/0

3.3.3.3 1 FULL/BDR 00:00:37 192.168.23.2 FastEthernet1/0

R2#

从R1测试到R3的

R1#ping 192.168.23.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.23.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 24/34/44 ms

R1#ping 3.3.3.3 source loopback 0

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 1.1.1.1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/49/68 ms

R1#

都好了

从R2上看,R3是BDR,把直连R3的接口权限提高下,然后清空ospf 进程

技术分享图片

R2(config)#int f1/0

R2(config-if)#ip ospf priority 2

R2(config)#end

R2#clear ip ospf process

Reset ALL OSPF processes? [no]: yes

R2#

*Mar 1 12:33:51.728: %OSPF-5-ADJCHG: Process 100, Nbr 1.1.1.1 on FastEthernet0/0 from FULL to DOWN, Neighbor Down: Interface down or detached

*Mar 1 12:33:51.764: %OSPF-5-ADJCHG: Process 100, Nbr 3.3.3.3 on FastEthernet1/0 from FULL to DOWN, Neighbor Down: Interface down or detached

R2#

*Mar 1 12:34:00.112: %OSPF-5-ADJCHG: Process 100, Nbr 1.1.1.1 on FastEthernet0/0 from LOADING to FULL, Loading Done

*Mar 1 12:34:00.836: %OSPF-5-ADJCHG: Process 100, Nbr 3.3.3.3 on FastEthernet1/0 from LOADING to FULL, Loading Done

R3已经是area 1的主选举路由了

配置IPV6的接口地址

R1(config)#ipv6 unicast-routing

R1(config)#int f0/0

R1(config-if)#ipv6 address 2001:12:12::1/64

R1(config-if)#

R2(config)#ipv6 unicast-routing

R2(config)#int f0/0

R2(config-if)#ipv6 address 2001:12:12::2/64

R2(config-if)#no sh

R2(config-if)#do ping 2001:12:12::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:12:12::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/27/44 ms

R2(config)#int f1/0

R2(config-if)#ipv6 address 2001:23:23::1/64

R2(config-if)#no sh

R3(config)#ipv6 unicast-routing

R3(config)#int f1/0

R3(config-if)#ipv6 ad

R3(config-if)#ipv6 address 2001:23:23::2/64

R3(config-if)#no sh

R3(config-if)#do ping 2001:23:23::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:23:23::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/27/44 ms

R3(config-if)#

精确宣告IPV6 路由地址

R1(config)#ipv6 router ospf 200

R1(config-rtr)#router-id 1.1.1.1

R1(config-rtr)#int f0/0

R1(config-if)#ipv6 ospf 200 area 0

唯一的区别是IPV6是在接口配置IPV4是在路由接口配置的

R2(config)#ipv6 router ospf 200

R2(config-rtr)#rou

R2(config-rtr)#router-id 2.2.2.2

R2(config-rtr)#int f0/0

R2(config-if)#ipv6 os

R2(config-if)#ipv6 ospf ?

R2(config-if)#ipv6 ospf 200 area 0

R2(config)#int f1/0

R2(config-if)#ipv6 ospf 200 area 1

R3(config)#ipv6 router ospf 200

R3(config-rtr)#router-id 3.3.3.3

R3(config-rtr)#int f1/0

R3(config-if)#ipv6 ospf 200 area 1

R3(config-if)#e

R3#sh run int f1/0

在各路由上看IPV6的邻居

R1#sh ipv6 ospf neighbor

Neighbor ID Pri State Dead Time Interface ID Interface

2.2.2.2 1 FULL/BDR 00:00:32 3 FastEthernet0/0

R1#

R2#sh ipv6 ospf neighbor

Neighbor ID Pri State Dead Time Interface ID Interface

1.1.1.1 1 FULL/DR 00:00:38 3 FastEthernet0/0

3.3.3.3 1 FULL/BDR 00:00:31 3 FastEthernet1/0

R2#

R3#sh ipv6 ospf neighbor

Neighbor ID Pri State Dead Time Interface ID Interface

2.2.2.2 1 FULL/DR 00:00:39 4 FastEthernet1/0

从R1 R3互通验证

R1#ping 2001:23:23::2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:23:23::2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/41/48 ms

R1#

R3#ping 2001:12:12::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:12:12::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/44/48 ms
