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.

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.

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:

set service broadcast-relay id <n> disable

In addition you can also disable the whole service without removing the configuration by:

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!
