You are using IBGP with route reflection in your Clos IP fabric.
Which feature must you enable to allow the route reflector to advertise multiple versions of a route instead of only the best version?
A. multipath
B. multihop
C. AS override
D. BGP ADD-PATH
Correct Answer: A
Explanation/Reference:
Explanation:
BGP typically selects only one best path for each prefix and installs that route in the routing table. When BGP multipath is enabled, the device selects multiple equal-cost EBGP paths as the best paths to reach a given destination, and all these paths are installed in the routing table. BGP advertises only the active path to its neighbors. However, you can configure BGP to advertise multiple paths to the same destination for redundancy and load balancing.
