network: add automatic configuration for the networks created by nspawn --network-zone= This way, they "just work", similar to --network-veth behaves, as long as networkd is enabled and running on all involved nodes. 2016-05-06 21:03:40 +02:00			`# This file is part of systemd.`

network: allow LLDP packets to cross non-customer bridges for container network interfaces This changes the default .network files we ship for nspawn containers to set EmitLLDP=customer-bridge in order to allow propagation of the LLDP packets across bridges. This is useful so that "networkctl status" shows all peers connected to a virtual container network, collecting this data via LLDP. This is safe since the default configuration for these interfaces does not bridge these links to external interfaces, but relies on IP routing for this. 2016-05-06 22:44:13 +02:00			`EmitLLDP=customer-bridge`
