Graceful restart (GR) is one of the high availability (HA) technologies, which comprise a series of comprehensive technologies such as fault-tolerant redundancy, link protection, faulty node recovery, and traffic engineering. As a fault-tolerant redundancy technology, GR ensures normal forwarding of data during the restart of routing protocols to prevent interruption of key services. Currently, GR …

When BGP restarts, the peer relationship is re-established and the forwarding is interrupted. After Graceful Restart (GR) is enabled, traffic interruption can be avoided. The following roles are involved in the GR process: GR restarter: indicates a device that performs GR caused by a fault or triggered by the administrator. The GR restarter must be …
