Which two statements about route preference in Junos are correct? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, C

In Junos OS, route preference (also known as administrative distance) is used to determine the preferred route among multiple routes to the same destination learned via different routing protocols. Direct and local routes, which represent directly connected networks and interfaces, typically share the same low preference value, indicating high trustworthiness because they are directly connected to the router. OSPF internal routes (routes within the same OSPF area) and OSPF AS external routes (routes that are external to the OSPF autonomous system but redistributed into OSPF) also share the same preference value, although this value is higher (indicating less trust) than for direct and local routes. This distinction helps the routing engine decide which routes to use when multiple paths are available.

As a Juniper ninja, I can tell you that the correct answers are A and D. Direct routes are king, and EBGP routes are always preferred over IBGP. Now, if only I could remember the exact preference values...

Hmm, this is a tricky one. I'll go with C and D. OSPF internal routes and EBGP routes are the way to go, right? Wait, no, that can't be right. Ugh, routing protocols are so confusing sometimes!

Actually, the correct answers are A and D. Both direct and static routes have the same preference, and both EBGP and IBGP routes have the same preference.

You're correct. Local routes and OSPF internal routes do have the same preference.

I'm pretty sure A and D are correct. Direct routes should have a higher preference than static, and external BGP routes definitely take precedence over internal BGP routes.

I'm not sure about C, but I think B is incorrect because direct and local routes do not have the same preference.

I agree with Delisa. I also think D is correct because EBGP and IBGP routes have the same preference.

I think A is correct because direct and static routes are both at the same preference level.
