JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2023) — Question 85

When building an interprovider VPN. you notice on the PE router that you have hidden routes which are received from your BGP peer with family inet labeled-unicast configured.

Which parameter must you configure to solve this problem?

Answer options

• A. Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
• B. Under the protocols mpls hierarchy, add the traffic-engineering parameter.
• C. Under the family inet labeled-unicast hierarchy, add the explicit null parameter.
• D. Under the protocols ospf hierarchy, add the traffic-engineering parameter.

Correct answer: A

Explanation

The correct answer is A because adding the resolve-vpn parameter under the family inet labeled-unicast hierarchy allows the PE router to properly handle the hidden routes from the BGP peer. The other options do not address the issue of hidden routes in the context of labeled unicast and therefore would not solve the problem.
