If primarily LSPs need to be set up, LDP should be used RSVP sets up independent point to point LSPs. LSPs from multiple ingresses use the same label to reach the egress (multi-point to point LSP) Label bindings automatically established for specific FECs According to them, it looks like the sender is begging for a response. The French people considered this initialism old-fashioned and formal. It is a French phrase that is used to get the confirmation of an invitation.

This term is typically written on an invitation to indicate that the host has requested the guest to confirm their attendance by stating whether or not they will attend the party. It is an initialism that means please respond. RSVP Full Form RSVP is an abbreviation of the French phrase Rpondez s’il vous plat, which means please respond.

LDP vs RSVPīelow table differentiates between MPLS LDP and RSVP(-TE) – PARAMETERĮasy to configure. The full form of RSVP is Rpondez S’il Vous Plat. RSVP is the primary choice if we need to perform Traffic Engineering ie FRR, DiffServ-TE, Explicit Routing etc. The RSVP-TE (traffic extension) protocol is an addition to the RSVP protocol with extensions to allow it to set up optical paths in an agile optical network. It is mainly used to provide QoS and load balancing across the network including optical Core network. RSVP-TE is used to establish MPLS transport LSPs for meeting traffic engineering requirements. In the case of MPLS LDP, Label bindings are established automatically for specific FECs (behaviour is different by different vendors). LSR further establishes label switched paths through a network by mapping network-layer routing information to data-link layer path. LDP is an abbreviation for Label Distribution Protocol that defines a set of process and messages by which one LSR (Label Switched Router) informs another of the label bindings.
