&ditem(RMR_BIND_IF) The interface to bind to listen ports to. If not defined 0.0.0.0 (all interfaces) is assumed.
- &ditem(RMR_RTG_SVC) The port RMR will listen on for route manager connections. If not defined 4561 is used.
+ &ditem(RMR_RTG_SVC) 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 &cw(routemgr:4561) is assumed.
+
+ &ditem(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.
+
+ &ditem(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.
&ditem(RMR_SEED_RT) Where RMR expects to find the name of the seed (static) route table. If not defined no static table is read.
