Which protocol uses dynamic address mapping to request the next-hop protocol address for a specific connection?
Frame Relay inverse ARP|
static DLCI mapping|
Frame Relay broadcast queue|
dynamic DLCI mapping|
Dynamic address mapping uses Frame Relay Inverse ARP to request the next-hop protocol address for a specific connection, given its known DLCI. Inverse ARP requests are entered in an address-to-DLCI mapping table on the router or access server; the table is then used to supply the next-hop protocol address or the DLCI for outgoing traffic.
