Configuring RIPng NSR

Nonstop routing (NSR) backs up RIPng routing information from the active process to the standby process. After an active/standby switchover, NSR can complete route regeneration without tearing down adjacencies or impacting forwarding services.

NSR does not require the cooperation of neighboring devices to recover routing information, and it is typically used more often than GR.

IMPORTANT:

A device that has RIPng NSR enabled cannot act as GR restarter.

To enable RIPng NSR:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter RIPng view.	ripng [ process-id ] [ vpn-instance vpn-instance-name ]	N/A
3. Enable RIPng NSR.	non-stop-routing	By default, RIPng NSR is disabled. RIPng NSR enabled for a RIPng process takes effect only on that process. If multiple RIPng processes exist, enable RIPng NSR for each process as a best practice.
