  You are using an IBGP route reflector within your network. Your route reflector has received the 2001:1:2::/64 prefix, but it is not advertising the prefix to its cluster members. After examining the route reflector, you notice the output shown in

  the exhibit.

  Which configuration statement causes the route reflector to transmit the route to its IBGP peers?

  A. set protocols bgp group ibgpv6 advertise-inactive

  B. set protocols bgp group ibgpv6 accept-remote-nexthop

  C. set protocols bgp group ibgpv6 multipath

  D. set protocols bgp group ibgpv6 include-mp-next-hop
