Managing LDP

LDP (Label Distribution Protocol), defined by RFC 5036 [http://tools.ietf.org/html/rfc5036], is a protocol that

enables an MPLS capable router to exchange MPLS label information. The labels are distributed in both directions

so that an LSP (Label Switched Path) can be established and managed within an MPLS network dynamically, as

opposed to configuring static routes. LDP takes advantage of already established routing information (using OSPF

or IS-IS) to distribute label information amongst the MPLS enabled routers).

LDP works by enabling Label Switch Routers (LSRs) to discover and bind labels to their neighbors within the

MPLS network. The LSRs then identify their peers and exchange their label information with one another. Label

information is stored in Label Information Base (LIB) and Label Forwarding Information Base (LFIB) tables.
