网卡配置如下:
IPv6-Test# ifconfig
dc0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> mtu 1500
options=8<VLAN_MTU>
inet6 fe80::201:e8ff:fe00:7f86%dc0 prefixlen 64 scopeid 0x1
inet 10.10.1.13 netmask 0xffffff00 broadcast 10.10.1.255
ether 00:01:e8:00:7f:86
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
vr0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::213:46ff:fe8f:425e%vr0 prefixlen 64 scopeid 0x2
ether 00:13:46:8f:42:5e
media: Ethernet autoselect (none)
status: no carrier
bfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet6 fe80::20b:dbff:feba:a2cc%bfe0 prefixlen 64 scopeid 0x3
inet 192.2.2.1 netmask 0xffffff00 broadcast 192.2.2.255
ether 00:0b:db:ba:a2:cc
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500
lo0: flags=8048<LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5
inet 127.0.0.1 netmask 0xff000000
pc 连接的是bfe0, 可以正常通讯。
可是dc0 和vr0 都是报文可以发出但不能收进,比如ping对端,本地能否发送arp, 对端也可以回arp, 但是本地收不到这个包。
如果静态绑定mac/ip, 那么icmp echo 可以出去,对端也回echo reply, 但是本地收不到这个包。
判断是否收到包的依据是tcpdump
网线是好的,而且直联,插bfe0就是好的,另外两个口就是不行。
另:设备是用来测v6的,不过现在v4都不通。v6发包时,情况一样,nd报文可以出去,对方回了,但tcpdump显示没有收到
