MAC/IP advertisement routes advertise the MAC addresses that can be reached through the VTEP is a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. EVPN is a feature that provides control plane learning and signaling for VXLAN networks. MAC/IP advertisement routes are one of the types of routes that EVPN uses to advertise MAC and IP addresses of hosts connected to VTEPs2.

IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN is not a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. IMET routes are one of the types of routes that EVPN uses to advertise multicast information for VXLAN networks. IMET routes advertise the IP addresses of VTEPs that can join multicast groups for VXLAN segments2.

The aggregation layer operates at Layer 2 only, and the core provides Layer 2 and Layer 3 functions is not a use case for implementing Virtual Switching Extension (VSX) at the core for a data center that has a three-tier topology with ArubaOS-CX switches at each layer. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX can be implemented at any layer of the data center network, but it is more common to implement it at the aggregation or leaf layer, where it can provide Layer 2 and Layer 3 functions. The core layer typically operates at Layer 3 only and does not require VSX2.

The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network is a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN can support both IPv4 and IPv6 overlay networks over an IPv4 or IPv6 underlay network2.

Different virtual MAC must be used for IPv4 and IPv6 Active Gateway is not a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Active Gateway is a feature that provides first-hop redundancy for hosts connected to VTEPs using anycast gateway addresses. Active Gateway can use the same virtual MAC address for both IPv4 and IPv6 protocols on the same VNI2.

Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs' processes is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would create unnecessary complexity and overhead on Switch-1, and it would not guarantee optimal routing between the VRFs. A better strategy would be to use inter-VRF routing or route leaking on Switch-1, which allows direct communication between different VRFs without requiring redistribution1.

Place all three VRFs in the same OSPF process on Switch-1 is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would not work because OSPF does not support multiple VRFs in the same process on ArubaOS-CX switches. Each VRF must have its own OSPF process with a unique process ID1.

A Layer 3 VLAN interface is an interface that can be assigned an IP address and attached to a VRF. A VRF allows multiple instances of a routing table to co-exist within the same router. By attaching a Layer 3 VLAN interface to a VRF, you can isolate the traffic of that VLAN from other VLANs and routing domains12. This can enhance security and performance of the network.

In the Enhanced Transmission Selection (ETS) Local advertisement section is not where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX on an ArubaOS-CX switch interface. The ETS Local advertisement section shows the priority groups and bandwidth allocation that the switch advertises to the CNA, but it does not show whether the CNA has accepted them or not. To see whether the CNA has accepted the application priorities advertised with DCBX, you need to look at the Application Priority Local advertisement section, which shows the application protocol identifier (APPID) and priority values that the switch advertises to the CNA, and compare them with the Application Priority Remote advertisement section, which shows the APPID and priority values that the CNA advertises to the switch1.
