What are two functions of LDP?
What are two functions of LDP?
LDP is used to build and maintain LSP databases that are used to forward traffic through MPLS networks. LDP can be used to distribute the inner label (VC/VPN/service label) and outer label (path label) in MPLS. For inner label distribution, targeted LDP (tLDP) is used.
What protocol does LDP use?
LDP uses well-known (UDP and TCP) port number 646. The source address used for an LDP session can be set by adding the transport address TLV to the hello message.
How does LDP work?
LDP is a protocol that automatically generates and exchanges labels between routers. Each router will locally generate labels for its prefixes and will then advertise the label values to its neighbors. It’s a standard, based on Cisco’s proprietary TDP (Tag Distribution Protocol).
What are two types of LDP messages?
LDP Messages Announce and maintain LSRs on networks. Hello messages are discovery messages. Establish, maintain, and terminate sessions between LDP peers. Initialization and Keepalive messages are session messages.

What is label space in MPLS?
Per-Interface label space: MPLS labels are assigned per FEC per interface. This means that MPLS packets are forwarded based on both the incoming label and the incoming interface. This mode is used cell mode MPLS implementations. Per Platform label space: MPLS labels are assigned per FEC per platform.
What is difference between MPLS LDP and RSVP?
2 commonly used terms in MPLS are LDP and RSVP-TE. While the former relates to easy provisioning in MPLS setup, the latter i.e. RSVP-TE is related to guarantee bandwidth for traffic communication. LDP setups LSPs based on routing data, whereas RSVP setups additional traffic engineered LSPs.
What is LDP shipping?
What is the LDP cost? Landed Duty Paid (LDP) price is the final amount paid by a buyer for the goods they have had manufactured. The LDP price includes all duty, shipping and logistics and taxes as well as the manufacturing fee for the products.
