The correct answer is B. Change the MLDP peer IP address to source loopback address on the receiver loopback address. For multicast VPNs using MLDP, the default MDT must be established correctly between the PEs. This requires the MLDP tunnel endpoints to use the loopback addresses of the source and receiver PEs, not the interface IPs shown. Configuring the MLDP peer IP address as the loopback…
Question
Refer to the exhibit. An engineer is implementing an MVPN solution between the source and the receiver. Streamers are connected and forwarding streams to the IPTV source. The DSL modem is receiving the multicast stream. Which action must the engineer perform in global mode so that receiver R also receives the stream?
Exhibit
Options
- AChange the mdt data threshold value on the source to 10 and change the mdt data threshold
- BChange the MLDP peer IP address to source loopback address on the receiver loopback address
- CChange the range of addresses in the data MDP pool to 255.
- DChange the vpn id value on the receiver to 65530:10.

Explanation
For multicast VPNs using MLDP, the default MDT must be established correctly between the PEs. This requires the MLDP tunnel endpoints to use the loopback addresses of the source and receiver PEs, not the interface IPs shown. Configuring the MLDP peer IP address as the loopback of the source on the receiver (and vice versa) ensures that the default MDT forms properly, allowing multicast streams to flow from the IPTV source to the receiver.
