Referring to the exhibit, which statement is true?

1. A. An IPv4 unicast realm can be enabled on each router.
2. B. A policy can be configured on r1 to redistribute 172.16.100.1/32 into OSPFv2, which would cause r3 to eventually learn the route and place it into inet 0.
3. C. A RIB group can be configured on r3 to copy that route into inet 0 because 172.16.100.1/32 exists in r3's inet6.0 table. — đáp án hiện tại
