Whether to delete routes from a Routing Protocol Manager (RPM) whose join to DC-RTM goes down. If this is set to TRUE then the routes are deleted after the time specified in the 'dead RPM timer' parameter. If the join between an RPM and DC-RTM goes down, typically because the RPM is no longer running, then the routes received from that RPM gradually become out of date. This parameter allows DC-RTM to continue to use these routes regardless of whether the RPM ever restarts, or to stop using them after a period of time. This period of time should represent the maximum amount of time for which the RPM would be down if this were only a temporary state of affairs. Changes to this field do not affect joins which have previously died, including those which are currently running a dead RPM timer.
