The correct answer is D. Configure R4 to be the RP and mapping agent. For Auto-RP you need at least one RP candidate and one mapping agent. By configuring R4 with both an ip pim rp-candidate (to announce itself as an RP) and ip pim autorp mapping-agent (to collect RP announcements and advertise the RP-to-group mappings), you enable dynamic RP…
Question
Refer to the exhibit. The network is configured for multicast using PIM-SM. A server connected to R3 streams multicast data to hosts located on R4. To support expected growth in the network, the network engineer with an employee ID: 123456789 has decided to implement Auto-RP to dynamically assign a rendezvous point (RP). Which action must be taken?
Exhibit
Options
- AConfigure the interfaces participating in multicast to be in sparse-dense mode
- BConfigure R3 as the BSR mapping agent
- CConfigure each router with a different loopback address to be used as the backup RP.
- DConfigure R4 to be the RP and mapping agent

Explanation
For Auto-RP you need at least one RP candidate and one mapping agent. By configuring R4 with both an ip pim rp-candidate (to announce itself as an RP) and ip pim autorp mapping-agent (to collect RP announcements and advertise the RP-to-group mappings), you enable dynamic RP discovery for the whole PIM-SM domain.
