For autoconfiguration, the order in which the MPLS servers are started does not matter, meaning that an IP Availability Manager source or an MPLS server source does not need to be running before the autoconfiguration program adds it as a source to another MPLS server. If a source application is not running, the destination MPLS server accepts the add source request and then periodically attempts to connect to the source application. When the source application becomes available, the destination MPLS server begins its import of topology.
