ping6自环可以，但ping6别的网卡不行，可是ping这个网卡对应的ipv4就行，为何？

我的是FC2,用的是2.6内核，相信ipv6已经打开了，但有个问题，我的情况如下，在打ifconfig时结果显示为
=================================
eth1 Link encap:Ethernet HWaddr 00:05:5D:06:69:AE

=========================
这说明我的已经有ipv6了，我打ping6 ::1
[root@Gaolinfeng root]# ping6 ::1 -c 2
PING ::1(::1) 56 data bytes
64 bytes from ::1: icmp_seq=0 ttl=64 time=0.132 ms
64 bytes from ::1: icmp_seq=1 ttl=64 time=0.122 ms

--- ::1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.122/0.127/0.132/0.005 ms, pipe 2
已经通了，说明ipv6已经启用了，可为什么打ping6 fe80::205:5dff:fe06:69ae就不行？我打相对应的ping 192.168.1.1都通了呀？

==================       

这是用ping6的结果如下：

[root@Gaolinfeng root]# ping6 fe80::205:5dff:fe06:69ae
connect: Invalid argument
这个ipv6地址是从ifconfig中查到的。\
