JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 3

You are implementing traffic engineering in your MPLS network. You must ensure that the MPLS routes are used to traverse your network. Your solution should not affect IGP routes in your route tables.
In this scenario, which traffic engineering setting will accomplish this behavior?

Answer options

• A. bgp-igp-both-ribs
• B. mpls-forwarding
• C. bgp-igp
• D. bgp

Correct answer: D

Explanation

The correct answer is D because setting the traffic engineering to 'bgp' allows for the use of MPLS routes without interfering with IGP routes. Options A, B, and C would either combine routing information or change the behavior of IGP routes, which is not desired in this scenario.
