Configuring BGP NSR
BGP nonstop routing (NSR) backs up BGP state and data information from the active BGP process to the standby BGP process. The standby BGP process takes over when any of the following events occurs:
The active BGP process restarts.
The IRF member device that runs the active BGP process fails.
An ISSU starts on the IRF member device that runs the active BGP process.
When both GR and NSR are configured for BGP, NSR has a higher priority than GR. The device will not act as the GR restarter. If the device acts as a GR helper, it cannot help the restarter to complete GR.
To configure BGP NSR:
