CCIE R&S 400-101 V5.1 Written Exam: Explain MLD
In this article, I will be discussing Cisco Explain MLD as part of Layer 2 Technologies and Layer 2 Multicast CCIE Routing and Switching (R&S) V5.1 exam blueprint topics.
Layer 2 Multicast
- Explain MLD
Let me summarize some of the key takeaways related to Explain MLD as relevant to CCIE Routing and Switching (R&S) V5.1 written exam blueprint topics.
Explain MLD Exam Essentials
- MLD is an IPv6 protocol that a host uses to request multicast data for a particular group.
- Devices use the MLD protocol to learn whether members of a group are present on their directly attached subnets. Hosts join multicast groups by sending MLD report messages.
- By default, IPv6 MLD snooping is globally disabled on the switch and enabled on all VLANs.
- Packets delivered to group members are identified by a single multicast group address. Multicast packets are delivered to a group using best-effort reliability, just like IPv6 unicast packets.
- Enabling PIMv6, statically binding a local multicast group or enabling link-local group reports automatically enable MLD
