Presented herein is a "control plane type" along with numbers in the calculation of diverse paths for Label Switch Path (LSP) diversity. The control plane type is published along with the Shared Risk Link Group (SRLG) value at the termination endpoint. This helps in determining the source control plane of the SRLG value. The control plane type publication is local to the node/endpoint and does not need any additional signaling.
