B. Apply the prepend policy as an import policy under group R1.
C. Configure the multipath multiple-as parameter under the global BGP configuration.
D. Apply the prepend policy as an import policy under group R3.
正解：C

A. OSPFv3 only supports IPv4.
B. OSPFv3 is not backward compatible with IPv4
C. OSPFv3 supports IPv4 only on interfaces with family inet6 defined
D. OSPFv3 supports both IPv6 and IPv4, but not in the same routing instance.
