### Keterangan terkait Network :
## enp1s0 dengan segment 192.168.124.0/24 = internet / provider network.
## enp5s0 dengan segment 192.168.100.0/24 = local / isoalted network.
## bro dengan slave nya adalah enp1s0 ==> jadi IP 192.168.124.0/24 di configurated pada br0

## Network interface to connect to the uplink network
# MicroCloud requires one network interface for connecting OVN to the uplink network. 
# This network interface must either be an unused interface that does not have an IP address configured, or a bridge.
# MicroCloud configures this interface as an uplink interface that provides external connectivity to the MicroCloud cluster.
