For VXLAN routing on a Cisco Nexus 9000 series switch where all leaf switches share the same gateway MAC and IP address, the configuration must enable the anycast gateway feature. This is achieved by setting the fabric forwarding anycast-gateway-mac to a common MAC address across all leaf switches and configuring the VLAN interface with the fabric forwarding mode anycast-gateway command. Option D provides the correct set of commands to accomplish this task, ensuring that the leaf switches can route traffic using the same gateway MAC and IP address, which simplifies the network design and eases the management of the VXLAN overlay.
References := The configuration steps are aligned with Cisco's best practices for VXLAN routing as described in the Cisco documentation and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials, which detail the process of setting up VXLAN and using anycast gateways

The command rpm -Uhv is used to upgrade or install an RPM package on Linux-based systems. In the context of upgrading bash on a Cisco Nexus 9000 Series Switch, this command would be used to install the new bash package from the provided file path.
