The correct answer is B. Use a unique, private BGP AS number for each Tier-0 gateway. BGP loop prevention relies on unique AS numbers. If the same AS is reused, routes may be dropped. In NSX VPC designs, assigning a unique private AS per Tier-0 gateway ensures clean routing without triggering loop detection. A: Timer adjustment affects convergence, not loop…
Question
An architect is developing a VMware Cloud Foundation (VCF) solution with NSX VPC Full Services Model for single tenant with the following requirement:
The configuration must prevent advertisements from being dropped by the BGP loop detection check. When designing the network architecture to support this solution, what element should be considered as part of the physical network design?
Options
- AAdjust the default BGP timers.
- BUse a unique, private BGP AS number for each Tier-0 gateway.
- CUse iBGP as the routing protocol between the Tier-0 gateway and the physical network.
- DConfigure edge datapath interface to transport only TEP traffic.

Explanation
BGP loop prevention relies on unique AS numbers. If the same AS is reused, routes may be dropped. In NSX VPC designs, assigning a unique private AS per Tier-0 gateway ensures clean routing without triggering loop detection. A: Timer adjustment affects convergence, not loop detection. C: iBGP with physical routers is non-standard and doesn't solve the loop issue. D: TEP traffic is unrelated to BGP routing loops.
