The NSX Tier-0 Gateway router must be configured to implement message authentication for all control plane protocols.
An XCCDF Rule
Description
<VulnDiscussion>A rogue router could send a fictitious routing update to convince a site's perimeter router to send traffic to an incorrect or even a rogue destination. This diverted traffic could be analyzed to learn confidential information about the site's network or used to disrupt the network's ability to communicate with other networks. This is known as a "traffic attraction attack" and is prevented by configuring neighbor router authentication for routing updates. This requirement applies to all IPv4 and IPv6 protocols that are used to exchange routing or packet forwarding information. This includes Border Gateway Protocol (BGP), Routing Information Protocol (RIP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Intermediate System to Intermediate System (IS-IS) and Label Distribution Protocol (LDP).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

To set authentication for BGP neighbors, do the following:
From the NSX Manager web interface, go to Networking >> Connectivity >> Tier-0 Gateways, and expand the target Tier-0 gateway.
Expand BGP. Next to BGP Neighbors, click on the number present to open the dialog, then select "Edit" on the target BGP Neighbor.
