Exam JN0-363 topic 1 question 21 discussion

the methods for communicating between routing instances are as follows: static route with a next-hop of next-table pointing to the appropriate routing table which contains more accurate information rib-groups to mirror routing information from one route-table to another. However, in many cases, in order to make this work, interface-routes also need to be mirrored. RIB Group policy can be used to constrain the routing information instance-import and instance-export statements configured within the individual routing-instances to leak routes from one table to another. Again, policy can be used here to constrain the routing information. This method is more straightforward than the rib-group method A final approach is to use physical interfaces or logical-tunnels to stitch routing-instances and use a routing protocol or static routes across this connection between the two routing-instances.

BD will be the correct

should be BD...Create the RIB group first, then filter on what is actually imported with an import policy

A. Use a non-forwarding instance: A non-forwarding instance is used for tasks that require routing information but do not participate in the actual packet forwarding. It does not directly facilitate the sharing of routes between routing instances. C. Create a forwarding instance: A forwarding instance is used for packet forwarding in Junos OS. While it's involved in the forwarding of packets, it's not a mechanism for sharing routes between routing instances. So, options B and D are the correct ways to share routes between routing instances in Junos OS.
