Configuring LDP GR

Before you configure LDP GR, enable LDP on the GR restarter and GR helpers.
To configure LDP GR:
Step
1. Enter system view.
2. Enter LDP view.
3. Enable LDP GR.
4. Configure the Reconnect
timer for LDP GR.
5. Configure
Forwarding State Holding
timer for LDP GR.

Configuring LDP NSR

MSR4000
To configure LDP NSR:
Step
1. Enter system view.
2. Enter LDP view.
3. Enable LDP NSR.

Configuring LDP-IGP synchronization

After you enable LDP-IGP synchronization for an OSPF process, OSPF area, or an IS-IS process, LDP-IGP
synchronization is enabled on the OSPF process interfaces or the IS-IS process interfaces.
You can execute the mpls ldp igp sync disable command to disable LDP-IGP synchronization on
interfaces where LDP-IGP synchronization is not required.

Configuring LDP-OSPF synchronization

LDP-IGP synchronization is not supported for an OSPF process and its OSPF areas if the OSPF process
belongs to a VPN instance.
