Abstract: In some examples, a controller for a network includes a path computation module configured for execution by one or more processors to obtain configuration information for at least one point-to-multipoint label switched path (P2MP LSP); obtain, from the network via at least one protocol, network topology information defining a network topology for the network; determine, based on the network topology, a first solution comprising first respective paths through the network for the at least one P2MP LSP; determine, after generating a modified network topology based on the network topology, a second solution comprising second respective paths through the network for the at least one P2MP LSP. The controller also includes a path provisioning module configured for execution by the one or more processors to configure the network with the solution of the first solution and the second solution having the lowest total cost.
