※ 引述《Paranoid (Gentoo 万岁 !!)》之铭言：
真不好意思又要麻烦您了~~~~
: 同时 tcpdump 您的 linux router 和 client 。
: 1. 在 client 跑 tcpdump (只听 ipv6 即可)
: 2. 在 router 跑 tcpdump (只听 ipv6 即可)
: 3. 在 client 跑 ping6 <IPv6 address> (跑久一点, 比较好看结果)
我照您的做了！

而router 的 eth0却没抓到！那eth1的话就是跟client抓到的一样
所以跟本没送出去，所以是router的问题~~~~~~
前一篇我说的protocol=0x29这是v4夹带出去v6时所定的, 在rfc2839有提到。
这样的结果应该是跟routing有关吧？
ping6 3ffe:3600:1e::352的封包是正常的， 有传出去。回来时hot limit=63。
我用的是redhat8.0有差吗？
您之前用的是redhat还是？
