You must ensure that r1's IPv4 loopback address exists in r3's inet 0 routing table.
Referring to the exhibit, which statement is true?

A. An IPv4 unicast realm can be enabled on each router.
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.
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.
D. A policy can be configured on r1 to redistribute 172.16.100.1/32 into OSPFv3, which would cause r3 to eventually learn the route and place it into inet 0.

Show Suggested Answer

Suggested Answer: C 🗳️
A RIB group is a way to have a routing protocol, in most cases, place information in multiple route tables.
Each RIB group is named and told where to place and retrieve route information. An example of a RIB group is: routing-options { rib-groups { test { import-rib [ inet.0 test.inet.0 ];
}
}
