Bridging Ethernet with NetworkManager on Rocky Linux 9 While Preserving DHCP and the MAC Address

On Ubuntu, it is common to use Netplan to attach an Ethernet interface to a Linux bridge. On Rocky Linux 9, however, NetworkManager typically manages networking.

Instead of Netplan, Rocky Linux uses nmcli to create a bridge and attach the physical network interface to it.

This article explains how to achieve the equivalent of an Ubuntu Netplan bridge configuration on Rocky Linux 9.
