+ This variabe supplies the host:port (or address:port) of the
+ Route Manager (route table generator) process. RMR will
+ attempt to connect to this address port combination and
+ request a route table. If it is desired to prevent RMR from
+ attempting to request a dynamic route table, the value of
+ this variable should be set to "-1." If not set
+ ``routemgr`` is assumed.
+
+ * - **RMR_CTL_PORT**
+ -
+ This is the port which RMR's route table collector thread
+ will use to listen for RMR messages from the route manager
+ (route table generator). By default this is 4561, and must be
+ unique for each RMR process running on the host/container.
+
+ * - **RMR_RTREQ_FREQ**
+ -
+ When a new route table is needed, the frequency that RMR
+ sends a route table request to the Route Manager defaults to
+ 5 seconds. This variable can be used to set the frequency to
+ a value between 1 and 300 seconds inclusive.
