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
R3(config)#inter f0/0
R3(config-if)#ipv6 address autoconfig default
R3(config-if)#end
R3#show ipv6 rou
R3#show ipv6 route
