Question

Your company is deploying an Azure Route Server in a hub VNet to enable dynamic route exchange between an SD-WAN network virtual appliance (NVA) and the Azure fabric. During configuration, the peering with the NVA fails to establish a BGP session. You confirm the NVA is running and reachable. Which configuration requirement must be satisfied for the BGP peering between Azure Route Server and the NVA to succeed?

Accepted Answer

The NVA must be configured to peer with the two private BGP peer IP addresses assigned to the Route Server and use a valid, non-reserved ASN.

Answer

The Route Server and the NVA must both be configured with the same ASN 65515 to form an iBGP session.

Answer

The NVA must be deployed in the same subnet named RouteServerSubnet as the Azure Route Server instance.

Answer

A user-defined route pointing to the NVA must be created on the RouteServerSubnet before BGP can be established.
