dhcpcd ipv6 在日志中过度添加/删除路由

这与路由器广告有关。目前，我ipv6rs从配置中删除并手动添加路由。有没有更好的方法来消除过多的日志？

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

答案1

当 dhcpcd 停止时，它不会像预期的那样清除自己添加的路由。但是，一旦 dhcpcd 重新启动并获取 dhcp，它将尝试再次添加路由，并会因为重复而删除自己的路由，但仍会将该路由标记为未添加。

解决方案（在修复此行为之前）是监视添加/删除的日志，然后删除它尝试添加的路由。在上述情况下：

sudo ip -6 route del default via fe80::201:5cff:fe63:c046 dev eth1

一旦完成后，dhcpcd 将重新添加路由并且保持安静。

答案2

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
