Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 32

You plan to configure OTV multicast. What must you enable to use SSM?

Answer options

• A. IGMPv3
• B. PIM-DM
• C. IGMPv2
• D. PIM-SM
• E. PIM Anycast-RP

Correct answer: A

Explanation

The correct answer is IGMPv3 because it supports Source-Specific Multicast (SSM) by allowing hosts to specify the source of the multicast streams they wish to receive. The other options, such as PIM-DM and PIM-SM, are related to multicast routing protocols and do not directly enable SSM functionality.
