Summary of MPLS LDP Configuration Tasks

After basic functions of MPLS LDP are configured, you can build an MPLS network using LDP. To ensure network reliability and security, you need to perform other configuration in addition to MPLS LDP.

Table 1 describes the MPLS LDP configuration tasks.

**Table 1** MPLS LDP configuration tasks
Scenario	Description	Task
Configure basic functions of MPLS LDP	You can build an MPLS network and establish LDP LSPs only after basic functions of MPLS LDP are configured.	Configuring Basic Functions of MPLS LDP
Configure LDP extensions for inter-area LSPs	This function enables LDP to search for routes according to the longest match rule and to establish multiple inter-area LDP LSPs based on the summarized route.	Configuring LDP Extensions for Inter-Area LSPs
Configure LDP reliability	The following reliability technologies can be used to improve MPLS network reliability: BFD for LDP LSPs: quickly detects faults on an LDP LSP and triggers a traffic switchover upon an LDP LSP failure, minimizing packet loss. Synchronization between LDP and IGP: solves the traffic loss problem when the primary LSP is faulty in networking where there are the primary and backup LSPs. LDP fast reroute (LDP FRR): provides link backup on an MPLS network. When the primary LSP fails, traffic is quickly switched to the backup LSP, minimizing traffic loss. LDP GR: ensures uninterrupted traffic transmission when an active/standby switchover or a protocol restart occurs on the neighboring device (GR Restarter). LDP GR helps GR Restarter to restart.

Configure LDP security mechanisms	LDP security mechanisms ensure security of LDP messages.	Configuring LDP Security Mechanisms
Configure non-labeled public network routes to be iterated to LSPs	After this configuration is performed on access devices, service data is forwarded to the Internet through tunnels. By dong this, core devices of the carrier do not need to learn many Internet routes, saving the routing table storage space and CPU resources.
