dmvpn中show ip nhrp 命令问题

豆豆豆

各位大仙，我想问下，我在完成DMVPN+eigrp的实验过程中，两个spoke建立连接，然后在spoke一端show ip nhrp查看的内容有点问题，望会的大仙们帮忙解决：
SPOKE1#ping 192.168.3.1 so
SPOKE1#ping 192.168.3.1 source 192.168.2.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.3.1, timeout is 2 seconds:
Packet sent with a source address of 192.168.2.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 136/234/340 ms
SPOKE1#show ip nhrp
172.16.1.1/32 via 172.16.1.1, Tunnel0 created 00:09:21, never expire
   Type: static, Flags: nat used
   NBMA address: 202.100.1.1
172.16.1.2/32 via 172.16.1.2, Tunnel0 created 00:00:06, expire 01:59:54
Type: dynamic, Flags: router unique nat local
   NBMA address: 202.100.2.1
     (no-socket)
172.16.1.3/32 via 172.16.1.3, Tunnel0 created 00:00:07, expire 01:59:53
   Type: dynamic, Flags: router nat used
   NBMA address: 202.100.3.1
问题1：routernat used 和router unique nat local是什么意思啊，我在这里没有做nat啊？？
问题2：在show ip nhrp后自己也形成了一条记录，这是起什么作用的？
问题3：no-socket是什么意思啊？？

router nat used 是说本地已经自动创建了去往WAN的NAT在outside接口，不行你可以show ip nat
