BFD (a fast detection technology) enabled on a device quickly identifies a fault and reports the fault to the appropriate protocol module after detecting a master/slave switchover on the neighboring device. This causes the protocol module to quit the GR. As such, BFD and GR cannot be used together.

Question

Quizplus · Accepted Answer

BFD (Bidirectional Forwarding Detection) and GR (Graceful Restart) can be used together. BFD provides rapid fault detection, while GR allows for a temporary disruption in control plane communication without affecting data plane forwarding. They complement each other by ensuring fast recovery and maintaining session continuity.
