CCIE Data Center (legacy) — Question 46

Which two statements about the ACI BGP route reflector policy are true? (Choose two.)

Answer options

• A. Route reflectors need not configure connectivity to external networks, but slight performance degradation can occur between border leaf and compute node leafs.
• B. Configuring route reflectors requires designating spines as route reflectors and providing the AS number.
• C. The ACI Fabric route reflectors use multiprotocol BGP to distribute external routes within the fabric.
• D. The BGP route reflector domain policy autonomous system number is configured during initial the APIC setup script, but it can be modified afterward.
• E. The BGP route reflector policy is configured under Fabric > Access Policies.

Correct answer: C, D

Explanation

Option C is correct because ACI Fabric route reflectors do indeed use multiprotocol BGP for distributing external routes. Option D is also correct as the autonomous system number can be modified after the initial setup. The other options are incorrect as they either misrepresent the functionality or configuration details of route reflectors.
