第4章 NDP协议

1.清除IPV6邻居

<R1>reset ipv6 neighbors all
Warning: This operation will delete all static and dynamic IPv6 ND entries and the configurations of all static IPv6 ND. Continue?[Y/N]:y
<R1>display ipv6 neighbors 

2.在R1的G0/0/0接口抓包，R1连通性测试R2直连地址

<R1>ping ipv6 -c 1 2012::2
  PING 2012::2 : 56  data bytes, press CTRL_C to break
    Reply from 2012::2 
    bytes=56 Sequence=1 hop limit=64  time = 60 ms
  --- 2012::2 ping statistics ---
    1 packet(s) transmitted
    1 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 60/60/60 ms

3.NDP解析过程两种报文，Type135：NS邻居请求报文，Type136：NA邻居通告报文
