Section 5.39.7
Managing LDP
LDP (Label Distribution Protocol), defined by RFC 5036 [http://tools.ietf.org/html/rfc5036], is a method of hop-
by-hop forwarding to determine the destination of packets without sending them up to the network layer (layer
3). When a router receives a packet, it looks up the incoming label in its forwarding table and then forwards the
packet to the next hop destination. This is opposed to looking up the IP header information in a packet, as in IP
forwarding.
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.
The following sections describe how to configure and manage LDP:
