Designing Cisco Enterprise Networks (ENSLD) — Question 107

When designing interdomain multicast, which two protocols are deployed to achieve communication between multicast sources and receivers? (Choose two.)

Answer options

• A. IGMPv2
• B. BIDIR-PIM
• C. MP-BGP
• D. MSDP
• E. MLD

Correct answer: C, D

Explanation

MP-BGP (C) and MSDP (D) are essential for enabling communication in interdomain multicast scenarios. While IGMPv2 (A) and MLD (E) are used for local network multicast group management, they do not facilitate interdomain communication. BIDIR-PIM (B) is a protocol for multicast routing but is not specifically focused on interdomain communication.
