Implementing Cisco Application Centric Infrastructure (DCACI) — Question 118

What is MP-BGP used for in Cisco ACI fabric?

Answer options

• A. MP-BGP VPNv4 AF is used as protocol on L3Out between a border leaf and an external router
• B. MP-BGP Layer 2 VPN EVPN AF is used to propagate L3Out routes that are received from a border leaf
• C. MP-BGP VPNv4 AF is used to propagate L3Out routes that are received from a border leaf to the fabric
• D. MP-BGP VPNv4 AF is used between spines in an ACI Multi-Pod fabric to propagate the endpoint

Correct answer: C

Explanation

The correct answer, C, is accurate because MP-BGP VPNv4 AF is indeed responsible for propagating L3Out routes from the border leaf to the fabric. Option A is incorrect as it describes a different relationship involving an external router, while B focuses on Layer 2 VPNs, which is not the primary function in this context. Option D misrepresents the role of MP-BGP between spines in this scenario.
