40_1: What are Routes and Gateways?

Routes

Routes define the path that network traffic takes to reach its destination. They determine how data packets move between different networks or subnets.

Each route consists of:

Destination: The target network or IP range.

Next Hop: The device (e.g., a gateway) responsible for forwarding the traffic.

Gateways

Gateways are network nodes that serve as entry and exit points for data between different networks. They help in forwarding traffic based on routing

rules.

40_2: Types of Routes and Gateways

Types of Routes

Local Routes – Enable communication within the same network or VCN.

Static Routes – Manually defined paths for directing traffic.

Dynamic Routes – Automatically learned and updated via routing protocols.

Types of Gateways

Internet Gateway (IGW) – Connects a private network to the public internet.

NAT Gateway – Provides outbound internet access to private instances without exposing them.

Service Gateway – Allows secure access to cloud provider services without using the internet.

Dynamic Routing Gateway (DRG) – Facilitates communication between different Virtual Cloud Networks (VCNs) or on-premises networks.

40_3: Advantages of Routes and Gateways

• Efficient Network Traffic Management – Routes ensure that data packets reach the correct destination efficiently.

• Enhanced Security – Gateways control data flow, preventing unauthorized access.

• Connectivity Between Networks – Enables communication between private and public networks, different subnets, or cloud services.

• Scalability – Supports large-scale cloud and enterprise network architectures.

40_4: Conclusion

Routes and gateways are fundamental components of any network, ensuring secure and efficient communication between devices, subnets, and external

networks. Proper configuration of routing tables and gateways enhances security, performance, and connectivity in both cloud and on-premise environments
