Refer to the exhibit. What is the meaning of the term dynamic as displayed in the output of the show framerelay map command shown?

• The Serial0/0 interface is passing traffic.
• The DLCI 100 was dynamically allocated by the router.
• The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server.
• The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud.
• The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse.

Explanation: Inverse Address Resolution Protocol (Inverse ARP) was developed to provide a mechanism for dynamic DLCI to Layer 3 address maps. Inverse ARP works much the same way Address Resolution Protocol (ARP) works on a LAN. However, with ARP, the device knows the Layer 3 IP address and needs to know the remote data link MAC address. With Inverse ARP, the router knows the Layer 2 address which is the DLCI, but needs to know the remote Layer 3 IP address. When using dynamic address mapping, Inverse ARP requests a nexthop protocol address for each active PVC. Once the requesting router receives an Inverse ARP response, itupdates its DLCI-to-Layer 3 address mapping table. Dynamic address mapping is enabled by default for all protocols enabled on a physical interface. If the Frame Relay environment supports LMI autosensing and Inverse ARP, dynamic address mapping takes place automatically. Therefore, no static address mapping is required.
