Smart Link NSR

Smart Link NSR

A master/slave switchover triggered by a system fault or performed by a network administrator when upgrading software or maintaining the system interrupts routing and causes traffic loss. Smart Link non-stop routing (NSR) can address this problem.

NSR ensures uninterrupted traffic transmission if a fault occurs on the control plane and a backup control plane is available to take over the traffic. During the switchover, the fault is transparent to the control plane of a neighbor.

Smart Link NSR uses the following approaches to synchronize data between main control boards in real time:
  1. Smart Link backs up the link status and instance forwarding status of interfaces but does not back up interface names or interface roles on the slave main control board. Interface names and interface roles can be restored on the slave main control board using the source data.
  2. If a master/slave main control board switchover is performed due to a fault on the device, the new main control board delivers the instance forwarding status of interfaces, ensuring that traffic is not interrupted.

Smart Link NSR is enabled on the device by default and does not need to be configured.
