Unfortunately if you split your network with multiple VLANs you loose +the ability of identifying your equipment. + +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! + +Configuration +------------- + +.. cfgcmd:: set service broadcast-relay id <n> description <description> + + A description can be added for each and every unique relay ID. This is + useful to distinguish between multiple different ports/appliactions. + +.. cfgcmd:: set service broadcast-relay id <n> interface <interface> + + The interface used to receive and relay individual broadcast packets. If you + want to receive/relay packets on both `eth1` and `eth2` both interfaces need + to be added. + +.. cfgcmd:: set service broadcast-relay id <n> port <port> + + The UDP port number used by your apllication. It is mandatory for this kind + of operation. + +.. cfgcmd:: set service broadcast-relay id <n> disable + + Each broadcast relay instance can be individually disabled without deleting + the configured node by using the following command: + +.. cfgcmd:: set service broadcast-relay disable + + In addition you can also disable the whole service without the need to remove + it from the current configuration. + +.. note:: You can run the UDP broadcast relay service on multiple routers + connected to a subnet. There is **NO** UDP broadcast relay packet storm! + +Example +------- + +To forward all broadcast packets received on `UDP port 1900` on `eth3`, `eth4` +or `eth5` to all other interfaces in this configuration. + +.. code-block:: none + + 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' |
