A.Dynamic address mapping uses Frame Relay Inverse ARP to request the next-hop protocol address for a specific connection on its known DLCI
B.Responses to Inverse ARP requests are entered in an address-to-DLCI mapping table on the router or access server which is used to supply the next-hop protoco address or the DLCI for outgoing traffic
C.Inverse ARP is enabled by default for all protocols enabled on the physical interface
D.Inverse ARP is configured using the following command under the Interface configuration ’frame-relaymap dlci （dlci number） protocol protocol-address’
E.Inverse ARP in Frame-Relay is synonymous of ARP in Ethernet
