    We describe a protocol to construct optical multicast trees in lambdaswitched networks running PIM-SM. Based on the MPLS architecture, the protocol maps a multicast tree constructed by PIM-SM onto point-to-multipoint LSPs that are connected to form an equivalent WDM multicast tree. LSP set-up request is receiver-initiated in the protocol. A mechanism to collect information about the capability of each WDM node along a path is used to provide receivers with sufficient information to form appropriate LSP set-up requests. This facilitates the set-up of LSPs, in particular in heterogeneous networks.
