# This test predominantly tests systemd-networkd DHCP server, by
|
|
# setting up a DHCP server and client, and ensuring they are mutually
|
|
# reachable via the DHCP allocated address.
|
|
# Two DHCP servers are set up on bridge VLANs, testing to make sure that
|
|
# bridge VLAN settings are correctly applied.
