Which two statements are correct in this scenario?

Your organization is implementing EVPN-VXLAN and requires multiple overlapping VLAN-IDs. You decide to use a routing-instance type mac-vrf to satisfy this request.

Which two statements are correct in this scenario? (Choose two.)

A. Host-facing interfaces must be configured using a service-provider style configuration.

B. Host-facing interfaces must be configured using enterprise-style configuration.

C. Spine-facing interfaces must be configured using an enterprise-style configuration.

D. The routing-instance service type can be VLAN-based.

Answer: AD

Explanation:

Understanding the Scenario:

EVPN-VXLAN deployments often involve scenarios where multiple tenants or applications require

overlapping VLAN IDs, which can be managed using the mac-vrf routing instance type. This allows

you to segregate traffic within the same VLAN ID across different tenants.

Host-facing Interface Configuration:

A. Host-facing interfaces must be configured using a service-provider style configuration: This is correct. In mac-vrf configurations, host-facing interfaces (those connecting end devices) typically follow a service-provider style configuration, where each customer or tenant’s traffic is isolated even if overlapping VLAN IDs are used.

B. Host-facing interfaces must be configured using enterprise-style configuration: This is incorrect for mac-vrf instances because enterprise-style configurations are more common in simpler, less segmented networks.

Routing Instance Service Type:

D. The routing-instance service type can be VLAN-based: This is correct. The service type in mac-vrf can indeed be VLAN-based, which is particularly useful in scenarios where VLAN ID overlap is needed between different tenants or services.

Reference: The mac-vrf instance type is powerful for handling complex multi-tenant environments in EVPN-VXLAN, especially when dealing with overlapping VLAN IDs across different segments of the network.
