三、地址检验
使用指令“show ipv6 interface brief”查询每个接口的IPv6地址配置情况：
1、 R1：
R1#show ipv6 interface brief
FastEthernet0/0 [up/up]
FE80::CE01:1FFF:FE64:0
2001:DB8:19:1::1
FastEthernet0/1 [up/up]
FE80::CE01:1FFF:FE64:1
2001:DB8:19:2::1
2、R2：
R2#show ipv6 interface brief
FastEthernet0/0 [up/up]
FE80::CE02:28FF:FEE8:0
2001:DB8:19:1::2
FastEthernet0/1 [up/up]
FE80::CE02:28FF:FEE8:1
2001:DB8:19:A::1
3、R3：
R3#show ipv6 interface brief
FastEthernet0/0 [up/up]
FE80::CE03:15FF:FEF8:0
2001:DB8:19:B::2
FastEthernet0/1 [up/up]
FE80::CE03:15FF:FEF8:1
2001:DB8:19:2::2
4、R4：
R4#show ipv6 interface brief
FastEthernet0/0 [administratively down/down]
FastEthernet0/1 [up/up]
FE80::CE04:24FF:FE20:1
2001:DB8:19:A:CE04:24FF:FE20:1
5、R5：
R5#show ipv6 interface brief
FastEthernet0/0 [up/up]
FE80::CE05:28FF:FE38:0
2001:DB8:19:B:CE05:28FF:FE38:0
FastEthernet0/1 [administratively down/down]
四、网络互ping测试
1、相邻网段互ping测试（R1 ping R2）：
2、不同网段互ping测试（R4 ping R1）：
3、全局互ping测试（R5 ping R4）：
五、报文分析
报文类型包括128、129、133、134、135、136类型：
1、128类型（回送请求）报文
作用：用于发送到目的节点，以使目标节点立即发回一个回送应答报文。
2、129类型（回送应答）报文
作用：当收到一个回送请求报文时，ICMPv6会用回送应答报文响应。
3、133类型（路由RS请求）报文
作用：很多情况下主机接入网络后希望尽快获取前缀进行通信，那么此时主机可以立刻发送RS报文，网络上的路由器将回应RA报文。RS报文的type字段值为133。
4、134类型（路由RA通告）报文
作用：每台路由器为了让二层网络上的主机和路由器知道自己的存在，定时都会组播发送RA报文，RA报文中会带有网络前缀信息，及其他一些标志位信息。RA报文的type字段值为134。
5、135类型（邻居NS请求）报文
作用：Type字段值为135，Code字段值为0，在地址解析中的作用类似于IPv4中的ARP请求报文。
6、136类型（邻居NA通告）报文
作用：Type字段值为136，Code字段值为0，类似于IPv4中的ARP应答报文。
