Introduction
The Cisco Certified Network Associate (CCNA) certification is one of the most sought-after IT certifications, validating foundational networking knowledge. A crucial topic in the CCNA curriculum is multicast MAC addresses, which play a significant role in network communication.
This article explores:
- What a multicast MAC address is
- The CCNA 1 V7 Checkpoint Exam structure
- Free CCNA 200-301 practice tests
- How Study4Pass can help in CCNA preparation
By the end, you'll have a clear understanding of these topics and access to valuable resources for exam success.
What Is a Multicast MAC Address?
A multicast MAC address is used in networking to deliver data packets to multiple devices simultaneously. Unlike unicast (one-to-one) or broadcast (one-to-all) communication, multicast (one-to-many) efficiently sends data to a selected group of devices.
Unicast vs. Multicast vs. Broadcast MAC Addresses
|
Type |
Description |
Example MAC Address |
|
Unicast |
Sent to a single device |
00:1A:2B:3C:4D:5E |
|
Multicast |
Sent to a group of devices |
01:00:5E:00:00:01 |
|
Broadcast |
Sent to all devices in a network |
FF:FF:FF:FF:FF:FF |
Structure of a Multicast MAC Address
Multicast MAC addresses follow a specific format:
- The first 24 bits (OUI) identify the manufacturer.
- The 25th bit is always set to 1 (indicating multicast).
- The last 23 bits map to an IP multicast group.
Example:
- IPv4 multicast address: 224.0.0.1
- Corresponding MAC: 01:00:5E:00:00:01
Common Multicast MAC Addresses
|
Multicast Group |
MAC Address |
|
All Hosts (224.0.0.1) |
01:00:5E:00:00:01 |
|
OSPF Routers (224.0.0.5) |
01:00:5E:00:00:05 |
|
RIP-2 Routers (224.0.0.9) |
01:00:5E:00:00:09 |
