UDP broadcast relay
|
|
-------------------
|
|
|
|
Certain vendors use broadcasts to identify their equipemnt within one ethernet
|
|
segment. Unfortunately if you split your network with multiple VLANs you loose
|
|
the ability of identifying your equiment.
|
|
|
|
This is where "UDP broadcast relay" comes into play! It will forward received
|
|
broadcasts to other configured networks.
|
|
|
|
Every UDP port which will be forward requires one unique ID. Currently we
|
|
support 99 IDs!
|
|
|
|
Example #1: To forward all broadcast packets received on `UDP port 1900` on
|
|
`eth3`, `eth4` or `eth5` to all other interfaces in this configuration.
|
|
|
|
.. code-block:: console
|
|
|
|
set service broadcast-relay id 1 description 'SONOS'
|
|
set service broadcast-relay id 1 interface 'eth3'
|
|
set service broadcast-relay id 1 interface 'eth4'
|
|
set service broadcast-relay id 1 interface 'eth5'
|
|
set service broadcast-relay id 1 port '1900'
|
|
|
|
Example #2: To Forward all broadcasts packets received on `UDP port 6969` on
|
|
`eth3` or `eth4` to the other interface in this configuration.
|
|
|
|
.. code-block:: console
|
|
|
|
set service broadcast-relay id 2 description 'SONOS MGMT'
|
|
set service broadcast-relay id 2 interface 'eth3'
|
|
set service broadcast-relay id 2 interface 'eth4'
|
|
set service broadcast-relay id 2 port '6969'
|
|
|
|
Disable Instance(s)
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
Each broadcast relay instance can be individually disabled without deleting the
|
|
configured node by using the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
set service broadcast-relay id <n> disable
|
|
|
|
In addition you can also disable the whole service without removing the
|
|
configuration by:
|
|
|
|
.. code-block:: console
|
|
|
|
set service broadcast-relay disable
|
|
|
|
.. note:: You can run the UDP broadcast relay service on multiple routers
|
|
connected to a subnet. There is **NO** UDP broadcast relay packet storm!
