JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2023) — Question 37

Your organization manages a Layer 3 VPN for multiple customers. To support advanced route filtering on your PE routers, you must advertise more than one BGP community on advertised VPN routes to remote PE routers.

Which routing-instance configuration parameter would support this requirement?

Answer options

• A. vrf-target import
• B. vrf-export
• C. vrf-target export
• D. vrf-import

Correct answer: B

Explanation

The correct answer is B, vrf-export, which allows the advertisement of multiple BGP communities for VPN routes. The other options, such as vrf-target import and vrf-target export, deal with the import and export of target communities but do not specifically enable the advertisement of multiple communities necessary for advanced route filtering.
