Issue:- when Sub interface state and main interface state is shut down , i did no shut of main interface only , but sub-interface state became up , running config shows interface is in shut state only
Looks like its not honoring the sub interface state .

1) ens161.4005 and ens161 both are in no shut state

We need to know if the sub is coming up because Zebra is coming up or if FR/R is missing the shutdown when bringing the interface up ... use iplinks to see the operating system output to see if zebra and the kernel are the same

Hi @riw777

Observing same behaviour with ip link also , ( ip link set ens161 up) bringing up sub-interface also
