ifdown scripts link will be installed with legacy network scripts.
Calling the legacy network scripts shows a warning about their deprecation.
[root@rhel-8 ~]# ifup eth0 WARN : [ifup] You are using 'ifup' script provided by 'network-scripts', which are now deprecated. WARN : [ifup] 'network-scripts' will be removed in one of the next major releases of RHEL. WARN : [ifup] It is advised to switch to 'NetworkManager' instead - it provides 'ifup/ifdown' scripts as well. Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)
