2.9 用Netsh显示IPv6配置
在一台运行Windows系统的计算上，可以用来来查看IPv6配置信息的常用命令如下所示。
- Netsh interface ipv6 show interface。
- Netsh interface ipv6 show address。
- Netsh interface ipv6 show route。
- Netsh interface ipv6 show neighbors。
- Netsh interface ipv6 show destinationcache。
2.9.1 Netsh interface ipv6 show interface
该命令可以显示出IPv6的接口列表，下面是输出信息的示例：
Idx Met MTU State Name
--- --- ----- ----------- -------------------
1 50 4294967295 enabled Loopback Pseudo-Interface 1
9 50 1280 enabled Local Area Connection* 6
6 20 1500 enabled Local Area Connection
10 50 1280 enabled Local Area Connection* 7
7 10 1500 disabled Local Area Connection 2
在默认情况下，接口名中含有星号（*）的是隧道接口。
2.9.2 Netsh interface ipv6 show address
该命令可以显示出各接口的IPv6地址列表，下面是输出信息的示例：
Interface 1: Loopback Pseudo-Interface 1
Addr Type DAD State Valid Life Pref. Life Address
--------- ----------- ---------- ---------- ------------------------
Other Preferred infinite infinite ::1
Interface 9: Local Area Connection* 6
Addr Type DAD State Valid Life Pref. Life Address
--------- ----------- ---------- ---------- ------------------------
Other Deprecated infinite infinite fe80::5efe:1.0.0.127%9
Interface 6: Local Area Connection
Addr Type DAD State Valid Life Pref. Life Address
--------- ----------- ---------- ---------- ------------------------
Public Preferred 29d23h59m59s 6d23h59m59s 2001:db8:21da:7:1f3e:9e51:2178:b9ob
Temporary Preferred 5d19h59m25s 5d19h59m25s 2001:db8:21da:7:a299:85ae:21da:59cc
Other Preferred infinite infinite fe80::713e:a426:d167:37ab%6
Interface 10: Local Area Connection* 7
Addr Type DAD State Valid Life Pref. Life Address
--------- ----------- ---------- ---------- ------------------------
Other Deprecated infinite infinite fe80::5efe:1.0.0.127%10
2.9.3 Netsh interface ipv6 show route
该命令可以显示出IPv6地址路由表中的路由条目列表，下面是输出信息的示例：
Publish Type Met Prefix Idx Gateway/Interface Name
------- -------- --- ------------------------ --- -----------------------
No Manual 256 ::/0 8 fe80::3cec:bf16:505:eae6
No Manual 256 ::1/128 1 Loopback Pseudo-Interface 1
No Manual 8 2001:db8::/64 8 Local Area Connection
No Manual 256 2001:db8::4074:2dce:b313:7c65/128 8 Local Area Connection
No Manual 256 2001:db8::b500:734b:fe5b:3945/128 8 Local Area Connection
No Manual 1000 2002::/16 11 Local Area Connection* 7
No Manual 256 fe80::/64 10 Local Area Connection* 9
No Manual 256 fe80::/64 8 Local Area Connection
No Manual 256 fe80::100:7f:fffe/128 10 Local Area Connection* 9
No Manual 256 fe80::5efe:10.0.0.3/128 17 Local Area Connection* 6
No Manual 256 fe80::b500:734b:fe5b:3945/128 8 Local Area Connection
No Manual 256 ff00::/8 1 Loopback Pseudo-Interface 1
No Manual 256 ff00::/8 10 Local Area Connection* 9
No Manual 256 ff00::/8 8 Local Area Connection
2.9.4 Netsh interface ipv6 show neighbors
该命令可以显示出接口缓存的内容，该缓存中会保存最新解析出来的下一跳地址的链路层地址（MAC地址），显示信息按照接口来分类，下面是输出信息的示例：
Interface 1: Loopback Pseudo-Interface 1
Internet Address Physical Address Type
-------------------------------------------- ----------------- -----------
ff02::16 Permanent
ff02::1:3 Permanent
Interface 8: Local Area Connection
Internet Address Physical Address Type
-------------------------------------------- ----------------- -----------
2001:db8::3cec:bf16:505:eae6 00-13-72-2b-34-07 Stale (Router)
2001:db8::4074:2dce:b313:7c65 00-00-00-00-00-00 Unreachable
2001:db8::6c4b:bf6d:201a:ccbf 00-00-00-00-00-00 Unreachable
fe80::3cec:bf16:505:eae6 00-13-72-2b-34-07 Stale (Router)
ff02::16 33-33-00-00-00-16 Permanent
Interface 10: Local Area Connection* 9
Internet Address Physical Address Type
-------------------------------------------- ----------------- -----------
fe80::b500:734b:fe5b:3945 255.255.255.255:65535 Unreachable
ff02::16 255.255.255.255:65535 Permanent
2.9.5 Netsh interface ipv6 show destinationcache
这个命令会显示目的缓存的内容，该缓存中会保存目的地址的下一条地址，显示信息按照接口来分类，下面是输出信息的示例。
Interface 8: Local Area Connection
PMTU Destination Address Next Hop Address
---- --------------------------------------------- -------------------------
1500 2001:db8::3cec:bf16:505:eae6 2001:db8::3cec:bf16:505:eae6
