Pre-configuration Tasks
Before configuring synchronization between LDP and static routes, complete the following
tasks:
l Enabling MPLS
l Configuring MPLS LDP in the system view and interface view
l Establishing LDP sessions between devices
Data Preparation
To configure synchronization between LDP and static routes, you need the following data.
No.
Data
1 Type and number of the outbound interface of a static route
2 Time during which a static route waits for an LDP session to be established, that is,
time of the Hold-down timer (optional)
2.8.2 Enabling Synchronization Between LDP and Static Routes
On an MPLS network with primary and backup LSPs, LSRs establish LSPs based on static
routes. By enabling synchronization between LDP and static routes on both ends of the two
links, you can avoid MPLS traffic interruption.
