Add example: set interfaces ethernet eth1 vif 21 address dhcp set interfaces ethernet eth1 vif 21 address dhcpv6 commit If network cable is unplugged: vyos-netlinkd[12681]: RTM_NEWLINK -> eth3.10, state=DOWN, mac=00:50:56:b3:9d:8e vyos-netlinkd[12681]: Stopping dhclient@eth3.10.service... vyos-netlinkd[12681]: Stopping dhcp6c@eth3.10.service...
