Abstract:
1. A method for controlling traffic forwarding at a Label Switched Router (LSR), comprising: defining one or more traffic forwarding capabilities (TFCs) associated with each of a plurality of data plane interfaces between said LSR and a peer LSR, wherein the one or more TFCs defined for at least one interface differs from the one or more TFCs defined for at least one other interface of the plurality of data plane interfaces; indicating said one or more defined TFCs for each of the plurality of data plane interfaces to said peer LSR via a label distribution protocol (LDP) message; and in response to said LSR receiving indication of agreement of said peer LSR to the one or more TFCs defined for at least one of the plurality of data plane interfaces, propagating traffic toward said peer LSR via the at least one agreed data plane interface, wherein traffic associated with the at least one agreed data plane interface is constrained in accordance with the corresponding one or more defined TFCs.
