CCNA（新版）-ipv6地址配置实验

by小世界http://redcisco.blog.163.com实验拓扑：

实验需求：

实验步骤：

1.配置左边部分--R1和R2

R1#conf t

R1(config)#ipv6 unicast-routing //开启IPV6功能

R1(config)#inter f0/0

R1(config-if)#ipv6 address 2001:1/64//报错信息

% Incomplete command.

R1(config-if)#ipv6 address 2012::1/64

R1(config-if)#no sh

R2#conf t

R2(config)#ipv6 unicast-routing 

R2(config)#inter f0/0

R2(config-if)#ipv6 address 2012::2/64

R2(config-if)#no sh

*Mar  1 00:04:54.171: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up

*Mar  1 00:04:55.171: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R2(config-if)#end

R2#show ipv6 inter f0/0//查看

FastEthernet0/0 is up, line protocol is up

  IPv6 is enabled, link-local address is FE80::CE01:DFF:FE08:0 

  Global unicast address(es):

    2012::2, subnet is 2012::/64 

  Joined group address(es):

    FF02::1

    FF02::2

    FF02::1:FF00:2

    FF02::1:FF08:0

  MTU is 1500 bytes

（省略）

//R1、R2连通性测试

R2#ping 2012::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2012::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/31/56 ms

2.配置右边部分--R2和R3

R2(config)#inter f1/0

R2(config-if)#ipv6 address 2023::2/64

R2(config-if)#no sh

*Mar  1 00:08:28.191: %LINK-3-UPDOWN: Interface FastEthernet1/0, changed state to up

*Mar  1 00:08:29.191: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/0, changed state to up

R3(config)#ipv6 unicast-routing 

R3(config)#inter f0/0

R3(config-if)#no sh

R3(config-if)#ipv6 address ?

  WORD                General prefix name

  X:X:X:X::X          IPv6 link-local address

  X:X:X:X::X/<0-128>  IPv6 prefix

  autoconfig          Obtain address using autoconfiguration

R3(config-if)#ipv6 address autoconfig（可以直接回车）//设备IPv6 地址为自动配置：

当接口配置为IPV6 address autoconfig后，系统会自动的发送RS请求，当网络中有设备在响应此请求，会收到RA回应信息。（此回应无详细IPV6地址，只有IPV6地址前缀）。设备会根据回应的IPV6地址前缀与本设备的当前端口的MAC地址做计算后，得到自己的IPV6地址。然后会用该地址发送DAD地址检测信息。如果检测通过后，系统就会认为此地址可以用，并将这个地址配置到自己的端口上面。

R3#show ipv6 interface f0/0

FastEthernet0/0 is up, line protocol is up

  IPv6 is enabled, link-local address is FE80::CE02:DFF:FE08:0 

  Global unicast address(es):

    2023::CE02:DFF:FE08:0, subnet is 2023::/64 [PRE]

      valid lifetime 2591984 preferred lifetime 604784

  Joined group address(es):

    FF02::1

    FF02::2

    FF02::1:FF08:0

  MTU is 1500 bytes

//测试R3#ping 2023::2 

Sending 5, 100-byte ICMP Echos to 2023::2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/38/104 ms

R3#ping 2012::2

Sending 5, 100-byte ICMP Echos to 2012::2, timeout is 2 seconds:

.....

Success rate is 0 percent (0/5)

R3(config-if)#ipv6 address autoconfig ?

  default  Insert default route

  <cr>

R3(config)#inter f0/0

R3(config-if)#ipv6 address autoconfig default 

R3(config-if)#end

R3#show ipv6 rou

R3#show ipv6 route
