尝试添加 IPv6 路由时收到“RTNETLINK 答案：参数无效”

当我尝试添加 IPv6 路由时收到一条错误消息：

root@lx-anielsen ~ $ ip -6 route add ::a:6:0/112 via ::a:4:1 dev eth1.1001
RTNETLINK answers: Invalid argument

我的界面配置如下：

root@lx-anielsen ~ $ ip -6 addr

    inet6 ::1/128 scope host

我正在使用 RHEL 6：

anielsen@lx-anielsen ~ $ cat /etc/issue
Red Hat Enterprise Linux Client release 6.3 (Santiago)
Kernel \r on an \m

我究竟做错了什么？

答案1

我想这就是正在发生的事情。

1）加载ipv6模块

modprobe ipv6

2）添加ipv6地址和路由

ip addr add 2001:IPV6:...2/64 dev eth1.1001
ip route add ::a:6:0/112 dev eth1.1001

3）尝试一下

答案2

根据 Michael Hampton 的评论，如果您的 IP/网络掩码组合无效，您通常会看到此错误消息。

使用子网计算器仔细检查您是否具有所需 IP 范围和子网大小的正确网络掩码。
