MPLS-LDP-STD-MIB

About this MIB

LDP is the core of MPLS and defines the messages and processing procedures involved in the label distribution process.

The Label Distribution Protocol (LDP) dynamically distributes FEC-label mapping information between LSRs to establish LSPs. LSPs can be established between two adjacent LSRs or terminate at the egress node of the network, so that all intermediate nodes in the network use label switching.

MPLS-LDP-STD-MIB is a public MIB defined by RFC 3815.
