2V0-41.24 Question 375
Select 2An organization has deployed an NSX-T Data Center environment with multiple Tier-0 and Tier-1 gateways. The administrator wants to configure NAT route redistribution for the Tier-0 gateway to advertise the NAT-ed IP ranges to the upstream physical routers. Which of the following steps are required to correctly configure NAT route redistribution?
- A
Enable route redistribution for NAT under the Tier-0 gateway's route redistribution settings.
- B
Set the NAT rule's action to 'DNAT' or 'SNAT' to enable redistribution.
- C
Add a redistribution rule for 'NAT' under the Tier-0 gateway's BGP settings.
- D
Configure the Tier-1 gateway to advertise NAT routes to Tier-0.
- E
Ensure that the NAT rules are applied to the uplink interface of the Tier-0 gateway.
Show answer and explanation
Correct answers: A, C
Explanation
To enable NAT route redistribution in an NSX-T environment, you must enable NAT route redistribution in the Tier-0 gateway's route redistribution settings and create a redistribution rule for 'NAT' under the Tier-0 gateway's BGP settings. These configurations ensure that NAT-ed IP ranges are advertised to upstream physical routers. Other steps, such as configuring NAT actions or applying rules to an interface, are necessary for NAT functionality but do not directly enable route redistribution.
- A. Correct.
This step is required to enable NAT route redistribution for the Tier-0 gateway. Without enabling this option, NAT-ed routes will not be advertised.
- B. Incorrect.
The NAT rule's action determines the type of NAT being applied (e.g., SNAT or DNAT), but it does not directly enable route redistribution.
- C. Correct.
Adding a redistribution rule for 'NAT' under the Tier-0 gateway's BGP settings ensures that NAT-ed routes are advertised via BGP to the upstream routers.
- D. Incorrect.
Tier-1 gateways do not control NAT route redistribution to external networks. This configuration is managed at the Tier-0 gateway.
- E. Incorrect.
While NAT rules are applied to the Tier-0 uplink interface, this alone does not enable route redistribution. Additional configuration steps are needed to advertise these NAT routes.
