Which two statements are correct regarding VPLS mesh groups? (Choose two.)
A.
Unicast packets destined to another PE router within the same mesh group are dropped by the local PE router.
B.
Unicast packets destined to another PE router in a different mesh group are dropped by the local PE router.
C.
Broadcast, multicast, and unicast packets of unknown origin received from a PE router are flooded to all local CE routers.
D.
Broadcast, multicast, and unicast packets of unknown origin received from a PE router are flooded to all remote PE routers.
A & C
Unicast packets originating within a mesh group are dropped if the destination is another PE router within the same mesh group. However, if the destination MAC address of the unicast packet is a PE router located in a different mesh group, the packet is forwarded to that PE router.
Flooding Unknown Packets Across Mesh Groups
Broadcast, multicast, and unicast packets of unknown origin received from a PE router are flooded to all local CE routers. They are also flooded to all of the PE routers in the VPLS routing instance except the PE routers that are a part of the originating PE router mesh group.

thank you for the link. I really needed verification on this
