CCIE Data Center (legacy) — Question 95

Which two statements about multicast routing are true? (Choose two.)

Answer options

• A. Multicast routes are used to directly forward traffic without making RPF checks.
• B. IPv6 static multicast routes are supported.
• C. You can define RPF routes for multicast when you want multicast data to diverge from the unicast traffic path.
• D. You can define RPF routes for multicast on border routers to enable reverse path forwarding to an external network.
• E. RPF routes for multicast can be redistributed.

Correct answer: C, D

Explanation

Answer C is correct because RPF routes can be defined for multicast to allow data to separate from unicast paths. Answer D is also correct as RPF routes on border routers aid in reverse path forwarding to external networks. Options A, B, and E are incorrect because they either misstate the functions of multicast routing or do not apply to RPF routes specifically.
