To provision two STP systems in a mated pair configuration, you must create a linkset for the communication path between the systems and make sure that the link type is set to a C-link. If you provision such a link, the Mate STP attribute on the STP screen is automatically configured, and appears as read-only (refer to Configuring STP Attributes). Load sharing of traffic is possible over routes that are assigned the same, lowest cost.
This section applies if the DSC - SP2000 Platform is provisioned as an STP.
