Hi all,
First I know little about ipv6.
I have two target. A and B,A and B connet with each other *directly* with line.and I can ping each other with ipv4
For A:
PHP Code:
[root@localhost leilyang]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:21:9B:80:51:68

For B:
PHP Code:

On the A , I ping6 2002:1::2, but fail to ping.
On the B. I run
PHP Code:
root@localhost:/netperf_image> tcpdump -n ip6
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
