The correct answer is B. Activate the source under BGP address-family ipv4 MDT on router RA. In an MVPN deployment you must explicitly activate the default (and data) MDT branch on each receiver’s PE so it will join the mLDP tree and pull in the multicast stream. On RA you do this by entering the address-family ipv4 mdt stanza under the MP-BGP neighbor for RC and…
Question
Refer to the exhibit. An engineer is implementing an MVPN solution between the source and the receiver. Streamers are connected and are forwarding streams to the AG1 source. The setup box is now receiving the multicast stream. Which additional action must the engineer take so that receiver RA also receives the stream?
Exhibit
Options
- ASet redistribute connected subnets under address-family ipv4 vrf IPTV on the receiver.
- BActivate the source under BGP address-family ipv4 MDT on router RA.
- CActivate the receiver under BGP address-family ipv4 MDT on router AG1.
- DSet redistribute connected subnets under address-family ipv4 vrf IPTV on the source.

Explanation
In an MVPN deployment you must explicitly activate the default (and data) MDT branch on each receiver’s PE so it will join the mLDP tree and pull in the multicast stream. On RA you do this by entering the address-family ipv4 mdt stanza under the MP-BGP neighbor for RC and issuing the neighbor <RC-loopback> activate command.
