我在VmWare工作站上运行的两个虚拟主机上设置了IPv6连接时遇到问题。 主机是CentOS 6.2 x86和x86-64。 即使它们在桥接networking上，并且同一网段上有一个RA路由器，它们也不接受来自路由器的广告。
cat /proc/sys/net/ipv6/conf/eth0/accept_ra返回1 ，我刷新了所有的ip6tables规则。
主机都是全新的安装，除了安装一些库和更换壁纸，我没有改变任何东西;）
我该怎么做/检查/ …？
这里是关于转发的内核文档中的相关位。 和路由器请求/广告。
forwarding - BOOLEAN Configure interface-specific Host/Router behaviour. Note: It is recommended to have the same setting on all interfaces; mixed router/host scenarios are rather uncommon. FALSE: By default, Host behaviour is assumed. This means: 1. IsRouter flag is not set in Neighbour Advertisements. 2. Router Solicitations are being sent when necessary. 3. If accept_ra is TRUE (default), accept Router Advertisements (and do autoconfiguration). 4. If accept_redirects is TRUE (default), accept Redirects. TRUE: **If local forwarding is enabled, Router behaviour is assumed.** This means exactly the reverse from the above: 1. IsRouter flag is set in Neighbour Advertisements. 2. **Router Solicitations are not sent.** 3. **Router Advertisements are ignored.**
