Why is the no shutdown command used after the no frame-relay inverse-arp command?

If you enter theno shutdowncommand first, Inverse ARP may cause Frame Relay tolearn Layer 2 to Layer 3 mappings that you may not want it to learn. By turning off FrameRelay Inverse ARP before issuing theno shutdowncommand, you ensure that only the statically mapped connections that you want are part of the Frame Relay maps.
