+# Smoke test edge01.waw in a multi-VM NixOS test.
+#
+# This brings up three VMs:
+# - dut/edge01
+# - bgpspeaker, which simulates bgp upstreams
+# - customs, which simulates customs.hackerspace.pl.
+#
+# We use EoIP to build up virtual ethernet links between the machines, and
+# to run VLANs on that. We don't just use plain 'vlans' from NixOS tests as
+# we actually want to run 802.1q ourselves from the edge01 config.
+#
+# Everything else is pretty much straightforward. Bring up everything, ping
+# stuff. We don't really test much else than internet routing.
+#
+# To run this:
+#  nix-build -A bgpwtf.machines.tests.edge01-waw
+#
+# To debug this:
+#  nix-build -A bgpwtf.machines.tests.edge01-waw.driver && result/bin/nixos-test-driver
