NEW QUESTION # 84
What is the purpose of the confederation identifier in a BGP confederation?
- A. It identifies the autonomous system that belongs to the confederation.
- B. It carries the AS number within the confederation's local autonomous system.
- C. It reflects the route reflector cluster ID within the confederation.
- D. It advertises routes outside of the confederation's autonomous system.
Answer: A
Explanation:
In BGP confederations, the confederation identifier represents the external AS number for the entire confederation. The BGP confederation splits a single large autonomous system (AS) into smaller, manageable sub-ASes. These sub-ASes use private AS numbers internally but appear as a single unified AS to external BGP peers. The confederation identifier ensures that external BGP peers see the confederation as one cohesive AS rather than multiple smaller ASes.
