to other interfaces. This enables support for e.g. Apple Airplay devices across
multiple VLANs.
+Since the mDNS protocol sends the AA records in the packet itself, the repeater

To enable mDNS repeater you need to configure at least two interfaces. To re-
broadcast all mDNS packets from `eth0` to `eth1` and vice versa run:
.. code-block:: none
- set service mdns repeater interface eth0
- set service mdns repeater interface eth1
+ set service mdns repeater interface 'eth0'
