Routing Components Flashcards
What is the purpose of Tier-0 gateways in VMware NSX?
Tier-0 gateways connect virtual and physical networks to provide external connectivity (North-South traffic) to containers and virtual machines in the data center.
What services do Tier-0 gateways offer?
Tier-0 gateways offer gateway services between VMware NSX and external networks.
What is required for the deployment and management of Tier-0 gateways?
Deployment of one or more VMware NSX Edge nodes is required for centralized configuration and management of Tier-0 gateways.
What types of routing protocols do Tier-0 gateways support?
Tier-0 gateways support static and dynamic routing protocols (e.g., BGP) towards the physical network.
How do Tier-0 gateways handle network traffic load balancing and fault tolerance?
Tier-0 gateways support equal-cost multipath (ECMP) routing, which enables load balancing and provides fault tolerance for external network traffic.
What is the purpose of Tier-1 gateways in VMware NSX?
Tier-1 gateways connect virtual machines and containers across different networks or segments, facilitating internal communication (East-West traffic).
What services do Tier-1 gateways offer?
Tier-1 gateways provide gateway services to the internal networks or segments.
How are Tier-1 gateways implemented?
Tier-1 gateways are implemented as a distributed solution across all participating transport nodes.
Do Tier-1 gateways use dynamic routing protocols?
No, Tier-1 gateways do not use any dynamic routing protocols.
How do Tier-1 gateways handle external connectivity?
Tier-1 gateways connect to a Tier-0 gateway for external connectivity.
How are segments connected in a multitier deployment using NSX?
Segments are connected to Tier-1 gateways, and the Tier-1 gateways are connected to the Tier-0 gateway.
When is a multitier deployment topology commonly used?
A multitier deployment topology is typically used when different teams or business units manage the Tier-0 and Tier-1 gateways.
Can you provide an example scenario of a multitier deployment?
An example scenario is when the cloud provider manages the Tier-0 gateways, and each tenant is responsible for its own Tier-1 gateway.
How are segments connected in a single-tier deployment using NSX?
Segments are connected directly to the Tier-0 gateway, without a Tier-1 gateway.
When is a single-tier deployment topology commonly used?
A single-tier deployment topology is commonly used when the same team or business unit manages all gateways
