You are asked to build a single export policy that can be applied to all devices to advertise only loopback IP addresses in the 172.16.0.0/24 subnet into your EBGP IP fabric. In this scenario, which two solutions would accomplish this task? (Choose two.)



  1. Option A
  2. Option B
  3. Option C
  4. Option D

Answer(s): B



When considering VRF routing-instances for network segmentation, which two statements are true? (Choose two.)

  1. A logical interface can participate in multiple VRFs.
  2. Multiple VRFs on a single device consolidate routing information to a single table.
  3. VRFs have independent routing tables.
  4. VRFs support overlapping subnets.

Answer(s): C,D

Explanation:

Virtual Routing and Forwarding (VRF) instances allow multiple virtual routing tables to exist on a single physical router. Each VRF has its own independent routing table, which allows network paths to be segmented without interference from other VRFs. This design supports overlapping IP address spaces, enabling the same IP subnet to be used in different VRFs without conflict.

What are two types of EVPN routes? (Choose two.)

  1. ES-lmport route target
  2. Ethernet segment
  3. MAC mobility
  4. MAC advertisement

Answer(s): C,D

Explanation:

In Ethernet VPN (EVPN), MAC mobility and MAC advertisement are crucial route types. MAC mobility is used to handle the movement of MAC addresses between different network locations, ensuring accurate and efficient traffic forwarding. MAC advertisement routes are used to advertise the presence of MAC addresses, enabling the correct forwarding of Ethernet frames in an EVPN environment.

You are considering deploying a MAC-VRF type routing instance with a VLAN-bundle service type. In this scenario, which two statements are correct? (Choose two.)

  1. It can be implemented in a bridge overlay architecture.
  2. VLAN normalization is supported.
  3. Multiple VLAN IDs per EVI are supported.
  4. It can be implemented in an ERB architecture.

Answer(s): A,C

Explanation:

A MAC-VRF (MAC Virtual Routing and Forwarding) instance with a VLAN-bundle service type is used in EVPN-VXLAN architectures. It can be implemented in a bridged overlay architecture where Ethernet segments are bridged across the EVPN-VXLAN network. This setup supports multiple VLAN IDs per Ethernet VPN Instance (EVI), enabling the segregation and transport of traffic from different VLANs over the same EVPN-VXLAN infrastructure.
