需要修改 PVE Host 裡面的 net 把 accept_ra 修改成 2 使用 sysctl 指令
root@pve:~# sysctl -a | grep net.ipv6.conf.all.accept_ra net.ipv6.conf.all.accept_ra = 1 net.ipv6.conf.all.accept_ra_defrtr = 1 net.ipv6.conf.all.accept_ra_from_local = 0 net.ipv6.conf.all.accept_ra_min_hop_limit = 1 net.ipv6.conf.all.accept_ra_mtu = 1 net.ipv6.conf.all.accept_ra_pinfo = 1 net.ipv6.conf.all.accept_ra_rt_info_max_plen = 0 net.ipv6.conf.all.accept_ra_rt_info_min_plen = 0 net.ipv6.conf.all.accept_ra_rtr_pref = 1 root@pve:~# sysctl -w net.ipv6.conf.all.accept_ra=2 net.ipv6.conf.all.accept_ra = 2
檢查修改狀況
root@pve:~# sysctl -a | grep net.ipv6.conf.all.accept_ra net.ipv6.conf.all.accept_ra = 2 net.ipv6.conf.all.accept_ra_defrtr = 1 net.ipv6.conf.all.accept_ra_from_local = 0 net.ipv6.conf.all.accept_ra_min_hop_limit = 1 net.ipv6.conf.all.accept_ra_mtu = 1 net.ipv6.conf.all.accept_ra_pinfo = 1 net.ipv6.conf.all.accept_ra_rt_info_max_plen = 0 net.ipv6.conf.all.accept_ra_rt_info_min_plen = 0 net.ipv6.conf.all.accept_ra_rtr_pref = 1
LXC 裡面修改網卡把 IPv6 改成 SLAAC
