这与路由器广告相关。 现在，我从configuration中删除ipv6rs并手动添加路由。 有没有更好的方法来消除过多的日志？

这里是目前的configuration：
hostname duid persistent option rapid_commit option domain_name_servers, domain_name, domain_search, host_name option classless_static_routes option ntp_servers require dhcp_server_identifier slaac private nohook lookup-hostname noipv6rs interface eth1 # ipv6rs # ipv6ra_own_default iaid 1 ia_pd 1/::/64 eth2/0/64
当dhcpcd停止时，不会按预期清除自己添加的路由。 但是，一旦dhcpcd重新启动并获取了dhcp，它将尝试再次添加路由，并且会因为重复而删除自己的路由，但仍将该路由标记为未添加。
解决scheme，直到此行为是固定的，是监视日志添加/删除，然后删除它正在尝试添加的路由。 在上面的情况下：
sudo ip -6 route del default via fe80::201:5cff:fe63:c046 dev eth1
一旦完成，dhcpcd将添加路由回来，并保持安静。
sudo ip -6 route del default via fe80::201:5cff:fe63:c046 dev eth1
（没有第二条路线）为我解决了这个问题。 我的操作系统是Debian 8 Jessie
