Huawei Exam H12-821_V1.0 Topic 4 Question 81 Discussion
Topic #: 4
BGP is generally applied to complex networks where routes change frequently. Frequent route flapping consumes a large number of bandwidth and CPU resources, and even affects the normal operation of the network. This is an unavoidable problem that cannot be solved in BGP.
BGP Route Flapping and Mitigation
While route flapping is a concern in large-scale networks, BGP employs mechanisms such as Route Dampening to mitigate its impact. Route dampening suppresses frequently flapping routes for a period of time to reduce resource consumption and network instability.
Therefore, it is incorrect to state that the issue cannot be resolved in BGP.
HCIP-Datacom-Core Reference
The mechanism of route dampening is detailed in the BGP optimization chapters.
