Show Suggested 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!

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.
