Abstract

A method, apparatus and computer program product for distribution of routing information used in a transport network is presented, in a transport network having a plurality of edge devices and core devices, a main instance of a protocol is used for shortest path and tree computation. A multicast tree is defined per Virtual Services Network (VSN) to distribute Link State Data Base (LSDB) updates that only apply to members of said VSN. Multicast trees are built using a secondary instance of the control protocol LSDB and wherein each VSN multicast tree represents a separate instance of the secondary instance of the control protocol LSD. LSDB updates are distributed that only apply to members of the VSN using the multicast tree for the VSN.
