What is the reserved Frame Relay DLCI range for multicasting?

1000 - 1015
1016 - 1020
1019 - 1022
1023 - 1030

The correct answer is: 1019 - 1022

The reserved Frame Relay Data Link Connection Identifier (DLCI) range for multicasting is found within 1019 to 1022. This specific range is designated for control and signaling purposes, including multicast traffic, which allows a single message to be transmitted to multiple destinations simultaneously. In Frame Relay networks, multicasting is essential for applications such as video conferencing or broadcast services where the same information needs to be sent to several users efficiently. This range facilitates the proper segmentation and management of multicast traffic, ensuring that the data is routed correctly to all intended recipients. Understanding these designated ranges is crucial for network administrators when configuring Frame Relay networks to ensure that multicast traffic is handled appropriately without interfering with standard point-to-point DLCIs.
