ACI Fabric Infrastructure

A network engineer needs to optimize a Cisco ACI Multi-Pod deployment. Both pods use the same pod policy group. The customer requires that inter-pod traffic not be lost during a planned or unplanned spine reload. Which action achieves this objective?

Explanation

Cisco ACI Multi-Pod uses MP-BGP EVPN between spine switches to exchange endpoint reachability across pods. Configuring every spine as a BGP route reflector provides redundant route-reflection paths, so a planned or unplanned reload of one spine does not remove the inter-pod control-plane path needed to sustain forwarding.
