|
||||
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
|
||||
does not need to forge the source address. Instead, the source address is of
|
||||
the interface that repeats the packet.
|
||||
|
||||
.. cfgcmd:: set service mdns repeater interface <interface>
|
||||
|
||||
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'
|
||||
set service mdns repeater interface 'eth1'
|
||||
|
||||
.. cfgcmd:: set service mdns repeater disable
|
||||
|
||||
mDNS repeater can be temporarily disabled without deleting the service using
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
set service mdns repeater disable
|
||||
|
||||
.. note:: You can not run this in a VRRP setup, if multiple mDNS repeaters
|
||||
are launched in a subnet you will experience the mDNS packet storm death!
