Referring to the exhibit, which type of NG MVPN route will be advertised by PE2 to PE1?
A.
Shared Tree Join C-Multicast route
B.
Source Tree Join C-Multicast route
C.
Source Active Auto-discovery route
D.
Leaf Auto-discovery route
Explanation:
C-Multicast routes include Shared tree join route. It was originated by receiver PE routers. It was originated
when a PE router receives a shared tree C-join (C-*, C-G) through its PE-CE interface.

A final answer.
The C-multicast route exchange between PE routers refers to the propagation of C-joins from receiver PE routers to the sender PE routers.
In a next-generation MVPN, C-joins are translated into (or encoded as) BGP C-multicast MVPN routes and advertised via the BGP MCAST-VPN address family toward the sender PE routers.
C-Multicast routes include Shared tree join route. It was originated by receiver PE routers. It was originated when a PE router receives a shared tree C-join (C-*, C-G) through its PE-CE interface.
Two types of C-multicast MVPN routes are specified:
• Type 6 C-multicast routes are used in representing information contained in a shared tree (C-*, C-G) join.
• Type 7 C-multicast routes are used in representing information contained in a source tree (C-S, C-G) join.
