What is the meaning of the term dynamic as displayed in the output of the show frame-relay map
command shown?
A.
The Serial0/0 interface is passing traffic.
B.
The DLCI 100 was dynamically allocated by the router
C.
The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server
D.
The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay
cloud
E.
The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned
through Inverse ARP
The term dynamic indicates that the DLCI number and the remote router IP address 172.16.3.1 are learned via the Inverse ARP process.
Inverse ARP is a technique by which dynamic mappings are constructed in a network, allowing a device such as a router to locate the logical network address and associate it with a permanent virtual circuit (PVC).
To use static mappings, turn Inverse ARP off.
We can check which type of mapping was configured with the command “show frame-relay map”:
– dynamic means the mapping was done using Inverse-Arp.
– static means the mapping was done manually (by command-line-interface).
Inv ARP – dynamic mapping
