Example
Run the display gtsm statistics command, and you can view the GTSM statistics in each slot,
including the total number of LDP, BGP, BGP4+, and OSPF packets and the number of packets
that are allowed to pass through or the number of dropped packets.

2.11 Configuring LDP GR

By configuring LDP GR, you can realize the uninterrupted forwarding during the master/slave
switchover or the protocol restart, which can limit the protocol flapping on the control plane.

2.11.1 Establishing the Configuration Task

Before configuring LDP GR, familiarize yourself with the applicable environment, complete
the pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
It is necessary to enable LDP GR to maintain normal forwarding and resume the LDP session
and establish LSPs after the switchover and system update.
Pre-configuration Tasks
Before configuring LDP GR, complete the following tasks:

NOTE
In practical applications, the system-level GR is usually configured in the hardware environment with dual
main control boards. In this manner, the service can be forwarded when the main control board fails.
