JNCIP-DC: Juniper Networks Certified Professional – Data Center (2024) — Question 31

Which three statements are correct about symmetric IRB routing with EVPN Type 2 routes? (Choose three.)

Answer options

• A. An L3 interface (IRB) is required for each local VLAN.
• B. Symmetric routing requires MAC-VRF.
• C. Symmetric routing is less efficient than asymmetric routing.
• D. Symmetric routing supports the EVPN service VLAN bundle.
• E. Symmetric routing requires an extra transit VNI for each VRF.

Correct answer: A, B, D

Explanation

The correct answers A, B, and D highlight the requirements and capabilities of symmetric IRB routing with EVPN Type 2 routes. Option C is incorrect because symmetric routing is not inherently less efficient than asymmetric routing; efficiency depends on the specific network design and traffic patterns. Option E is also incorrect as symmetric routing does not need an extra transit VNI for each VRF.
