This is a path to a loadable plugin. See also the +# auth_opt_* options described below. +# +# The auth_plugin option can be specified multiple times to load multiple +# plugins.

Set +# options for the bridges using the remaining parameters. You must specify the +# address and at least one topic to subscribe to. +# +# Each connection must have a unique name. +# +# The address line may have multiple host address and ports specified. See +# below in the round_robin description for more details on bridge behaviour if +# multiple addresses are used. Note that if you use an IPv6 address, then you +# are required to specify a port. +# +# The direction that the topic will be shared can be chosen by +# specifying out, in or both, where the default value is out. +# The QoS level of the bridged communication can be specified with the next +# topic option. The default QoS level is 0, to change the QoS the topic +# direction must also be given. +# +# The local and remote prefix options allow a topic to be remapped when it is +# bridged to/from the remote broker. This provides the ability to place a topic +# tree in an appropriate location. +# +# For more details see the mosquitto.conf man page. +# +# Multiple topics can be specified per connection, but be careful +# not to create any loops. +# +# If you are using bridges with cleansession set to false (the default), then +# you may get unexpected behaviour from incoming topics if you change what +# topics you are subscribing to. This is because the remote broker keeps the +# subscription for the old topic. If you have this problem, connect your bridge +# with cleansession set to true, then reconnect with cleansession set to false +# as normal. +#connection +#address [:] [[:]] +#topic [[[out | in | both] qos-level] local-prefix remote-prefix] + +# Set the version of the MQTT protocol to use with for this bridge. Can be one +# of mqttv311 or mqttv11. Defaults to mqttv311. +#bridge_protocol_version mqttv311 + +# If a bridge has topics that have "out" direction, the default behaviour is to +# send an unsubscribe request to the remote broker on that topic. This means +# that changing a topic direction from "in" to "out" will not keep receiving +# incoming messages. Sending these unsubscribe requests is not always +# desirable, setting bridge_attempt_unsubscribe to false will disable sending +# the unsubscribe request. +#bridge_attempt_unsubscribe true + +# If the bridge has more than one address given in the address/addresses +# configuration, the round_robin option defines the behaviour of the bridge on +# a failure of the bridge connection. If round_robin is false, the default +# value, then the first address is treated as the main bridge connection. If +# the connection fails, the other secondary addresses will be attempted in +# turn. Whilst connected to a secondary bridge, the bridge will periodically +# attempt to reconnect to the main bridge until successful. +# If round_robin is true, then all addresses are treated as equals. If a +# connection fails, the next address will be tried and if successful will +# remain connected until it fails +#round_robin false + +# Set the client id to use on the remote end of this bridge connection.

"clientid" +# remains valid for the time being. +#remote_clientid + +# Set the clientid to use on the local broker. If not defined, this defaults to +# 'local.'. If you are bridging a broker to itself, it is important +# that local_clientid and clientid do not match. +#local_clientid + +# Set the clean session variable for this bridge. +# When set to true, when the bridge disconnects for any reason, all +# messages and subscriptions will be cleaned up on the remote +# broker.

This controls how the bridge starts and +# can be one of three types: automatic, lazy and once. Note that RSMB provides +# a fourth start type "manual" which isn't currently supported by mosquitto. +# +# "automatic" is the default start type and means that the bridge connection +# will be started automatically when the broker starts and also restarted +# after a short delay (30 seconds) if the connection fails. +# +# Bridges using the "lazy" start type will be started automatically when the +# number of queued messages exceeds the number set with the "threshold" +# parameter. It will be stopped automatically after the time set by the +# "idle_timeout" parameter. Use this start type if you wish the connection to +# only be active when it is needed. +# +# A bridge using the "once" start type will be started automatically when the +# broker starts but will not be restarted if the connection fails. +#start_type automatic + +# Set the amount of time a bridge using the automatic start type will wait +# until attempting to reconnect.
