Selective advertising of BGP multiple paths

You can restrict BGP add-path to advertise contributor multiple paths only. Advertising all available multiple paths might result in a large overhead of processing on device memory and is a scaling consideration, too. You can limit and configure up to six prefixes that the BGP multipath algorithm selects. Selective advertising of multiple paths facilitates Internet service providers and data centers that use route reflector to build in-path diversity in IBGP.
