Which of the following statements about the Reverse Path Forwarding (RPF) mechanism are true? (Choose two.)
- Multicast RPF does not depend on unicast routing.
- All multicast protocols adopt the RPF mechanism.
- A router discards the received multicast packets if the packets fail the RPF check.
- The RPF mechanism has two functions: 1. It prevents multicast routing loops; 2. It avoids forwarding redundant multicast data packets.
