Question
Which of the following descriptions about the application of RPF in multicast data forwarding is incorrect?
Options
- AThe router will compare the incoming interface of the packet with the RPF interface of the RPF route.
- BIf they are consistent, the RPF check passes, indicating that the source path of the packet is correct and it will be forwarded downstream.
- CDuring the multicast data forwarding process, the receiving router will perform an RPF check on each received multicast data packet through the unicast routing table.
- DThe root router receives a multicast message, first checks the source address of the message, and then selects an optimal route based on the priority of the routing source. The outbound interface of this route is the RPF interface.
- EIf the RPF check fails, it indicates that the source path of the packet is wrong and the packet will be discarded.
