In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at the Services Aggregation layer. This layer is responsible for interconnecting different network services and typically includes more robust, higher-capacity devices capable of handling the route-reflection functions for EVPN VXLAN.

In an Aruba Networks fabric, route reflectors are used to optimize the distribution of BGP routes. The Services Aggregation layer, which is centrally located in the network topology, is best suited for this role due to its high availability and ability to efficiently manage routes between the core and access layers.

Therefore, if you were to click on the image provided, you would select the Services Aggregation layer to configure the Route-Reflector Persona.

In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.

In the design shown:

The BGP peering between agg-sw1 and agg-sw2 is being established using loopback interfaces as the BGP neighbor addresses (10.0.0.2 and 10.0.0.4)

When BGP peering uses loopbacks, you must configure the BGP session to originate updates from the same loopback interface that the neighbor’s address resolves to

Otherwise, the TCP session fails because:

The source IP does not match the configured neighbor remote-IP which is based on the loopback address

Aruba AOS-CX requirement:

“When configuring eBGP or iBGP neighbors using loopback interfaces, apply update-source under the IPv4 unicast address family so BGP uses the correct source interface for peering.”
