MPLS
MPLS supports multi-label and connection-oriented features.
MPLS LDP provides the loop detection mechanism, and prevents LSP loops.
If the administrator does not need to strictly control the LSP establishment,
LDP is recommended to create LSPs.

Overview of MPLS
-
This section describes the background and the technical positioning of MPLS.
-
Understanding MPLS
-
This section describes the working mechanism of MPLS from aspects, such as basic concepts, system and network structures, and LDP sessions.
-
Limitations and Precautions for MPLS
-
-
Configuring Static LSPs
-
You can set up a static Label Switched Path (LSP) by manually assigning labels to Label Switching Routers (LSRs). The static LSP applies stable, small-scale networks.
-
Configuring MPLS LDP
-
Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) defines the messages used during label distribution and the processing of the messages used to negotiate parameters between label switching routers (LSRs) and allocate labels to set up a label switched path (LSP).
-
Maintaining MPLS LDP
-
Maintaining MPLS LDP includes restarting LDP, clearing LDP statistics, monitoring the LDP running status, and detecting LSP connectivity.
-
Configuration Examples for MPLS
-
The following sections provide several examples for configuring MPLS LDP.
