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.

Data Center 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.
