Abstract
A method, apparatus, and machine readable storage medium is for management of an Inclusive Provider Multicast Service Interface (I-PMSI) tunnel for forwarding traffic for a given multicast flow is disclosed. Aspects of the method comprise: upon expiry of an S-PMSI_DELAY interval timer, switching the multicast flow from the I-PMSI tunnel to a Selective Provider Multicast Service Interface (S-PMSI) tunnel only if the number of active Source-to-Leaf (S2L) paths exceeds a defined first threshold of a number of S2L paths and otherwise resetting the S-PMSI_DELAY interval timer. Other aspects provide for switching the multicast flow from the I-PMSI tunnel to the S-PMSI tunnel only if the number of PE nodes associated with the S-PMSI tunnel interested in the multicast flow does not exceed a defined a second threshold. Other aspects, in the case of the S-PMSI tunnel being active, further comprise steps of switching the multicast flow from the S-PMSI tunnel to the I-PMSI tunnel if the number of S2L paths on S-PMSI in bypass exceeds a third defined threshold.
