1. A processor-implemented method for using one or more zoning configurations and one or more border gateway protocol (BGP) route maps in a non-volatile memory express over Fabric (NVMe-oF™) system, the method comprising:
in response to one or more BGP sessions having been established, using BGP peer information received at a centralized discovery controller (CDC) to apply a host identifier to a host and a subsystem identifier to a subsystem;
using the host identifier and the subsystem identifier to register at least one of the host or the subsystem with the CDC, the host and the subsystem being communicatively coupled to the CDC;
in response to a zone group having been configured that indicates that the host and the subsystem may access each other, using a route policy that is stored in an access list to create a route map; and
in response to the zone group being active, using the route map and the BGP peer information to communicate, in a BGP route advertisement, the route policy to the host that uses the route policy to update or to create an entry in a destination database that identifies a route, which the host should use to establish a connection with the subsystem.
