Abstract
In a receiver provider edge (PE) router, a method for supporting protocol independent multicast source-specific mode (PIM-SSM) using multicast resource reservation protocol-traffic engineering (mRSVP-TE) comprising the steps of receiving a protocol independent multicast (PIM) join message, in response to receiving the PIM join message sending a path message to a source PE router, wherein the path message is a multicast resource reservation protocol-traffic engineering (mRSVP-TE) message, and sending the PIM join message to the source PE router, wherein the path message and the PIM join message trigger setup of a data multicast data tree (MDT), creating a PIM state, and receiving multicast data traffic via the data MDT using the PIM state.
