dhcpcd ipv6 日誌中過多的添加/刪除路由

這與路由器廣告相關。現在，我ipv6rs從配置中刪除並手動添加了路線。有沒有更好的方法來消除過多的日誌？

這是目前的配置：

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

當 dhcpcd 停止時，它不會像預期的那樣清除自己添加的路由。但是，一旦重新啟動dhcpcd並獲取了dhcp，它會再次嘗試添加路由，並會因為重複而刪除自己的路由，但仍將路由標記為未添加。

在修復此行為之前，解決方案是監視日誌以進行添加/刪除，然後刪除它嘗試添加的路由。在上述情況下：

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

完成後，dhcpcd 將添加路由並保持安靜。
