label edge router (LER)

Resides at the network edge to initiate and terminate label switched paths and assign packets to forward equivalence class (FEC) as traffic enters the Multiprotocol Label Switching (MPLS) network.

label information base (LIB)

A table of incoming labels, outgoing labels, and interface mappings.

label retention mode

This mode (liberal or conservative) specifies whether or not the interface retains label bindings that it receives

label stack

MPLS uses a label stack, which can contain multiple labels. For example, in a stack containing two labels, the bottom label represents the egress Peripheral Equipment (PE) and the top label represents the next hop along the LSP. To move a packet across the network, LSRs swap out the top label to forward the packet to the next hop.

label switched path (LSP)

An end-to-end unidirectional tunnel between MPLS-enabled routers. Data travels through the MPLS network over LSPs from the network ingress to the network egress.

label switched router (LSR)

A core router that operates between the source and destination LERs in an MPLS network. LSRs strip off the existing label and applies a new label that tells the next-hop LSR how to forward the packet.

label use mode

This mode (immediate or not immediate) specifies when the interface uses the label for the next hop.
