JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2023) — Question 55

You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network.

In this scenario, which statement is correct?

Answer options

• A. You must use the same route-distinguisher value on both PE devices.
• B. You must assign a unique site number to each attached site's configuration.
• C. This type of VPN only supports Ethernet interfaces when connecting to CE devices.
• D. This type of VPN requires the support of the inet-vpn NLRI on all core BGP devices.

Correct answer: B

Explanation

The correct answer is B because each site's configuration must be uniquely identified to avoid conflicts. Option A is incorrect as different route distinguishers can be used for different PE devices. Option C is wrong since this type of VPN can support more than just Ethernet interfaces. Option D is not accurate as the inet-vpn NLRI support is not a requirement for all core BGP devices in this context.
