What must be configured to redistribute externally learned OSPF routes within the ACI fabric?

The correct answer is B. BGP Route Reflector. Once the border leaf learns the external routes, it can then redistribute the external routes of a given VRF instance to an MP-BGP address family (VPNv4 or VPNv6). MP-BGP maintains a separate BGP routing table for each VRF instance. Within MP-BGP, the border leaf switch advertise

Explanation

Once the border leaf learns the external routes, it can then redistribute the external routes of a given VRF instance to an MP-BGP address family (VPNv4 or VPNv6). MP-BGP maintains a separate BGP routing table for each VRF instance. Within MP-BGP, the border leaf switch advertises routes to a spine switch, which is a BGP route reflector. The routes are then propagated to all the leaf switches where the VRF instances are instantiated. infrastructure/guide-c07-743150.html
