According to the sources, the legend for this command explicitly identifies the code “D” as representing a Dynamic mapping . This indicates that the relationship between the tunnel IP address and the physical NBMA address was learned dynamically through the NHRP registration process rather than being manually configured as a Static (S) entry .
