MPLS v Module Summary LDP uses multicast UDP for neighbor discovery and unicast TCP for session establishment LDP is used for label distribution Overall network convergence is dependent on the IGP, not the MPLS convergence Frame-mode MPLS parameters include: –Per-platform label address space –Unsolicited downstream label distribution –Indepedent control for label allocation –Liberal label retention
