Overview:
Your connection is established with a single switch. This setup is straightforward but may have a single point of failure, meaning if the switch encounters an issue, connectivity could be disrupted.

Benefits:

• Simplicity: Easy to implement and manage.
• Cost-Effective: Lower initial setup costs due to fewer components.

Considerations:

• Single Point of Failure: If the switch fails, connectivity is lost until the issue is resolved.
• Limited Redundancy: Not suitable for mission-critical applications where uptime is essential.

Overview:
Your connection is established with one switch, but this switch is linked to two routers. This configuration eliminates the single point of failure associated with a single router by using HSRP, ensuring continuity of service if one router  fails.

Benefits:

• Increased Reliability: If one router fails, the other router continues to provide connectivity.
• Improved Uptime: Reduces the risk of downtime due to router failure.
• Better Performance: Suitable for businesses that need more reliability without complex infrastructure.

Considerations:

• Single Switch Dependency: The switch remains a single point of failure, though the dual routers provide a backup.

Overview:
Your connection is established with two switches, each connected to a different router. This setup provides the highest level of redundancy and reliability by eliminating single points of failure in both the switching and routing layers.

Benefits:

• Maximum Redundancy: Ensures that both switches and routers are redundant, providing continuous connectivity even if one component fails. Optimal Performance: Balances traffic across multiple paths for enhanced performance and reliability.
• High Availability: Ideal for critical applications and businesses that demand the highest uptime and fault tolerance.

Considerations:

• Complexity: More complex to configure and manage compared to single switch options.
• Higher Initial Costs: Increased infrastructure requirements may lead to higher setup costs.

Overview:
A single BGP session is established between our data center and the customer’s router. This option is straightforward and easy to manage, making it an excellent choice for customers who need reliable internet connectivity without complex configurations.

Benefits:

• Simplicity: Easy setup and management.
• Cost-Effective: Ideal for customers with smaller networks or those who don’t require redundancy.
• Efficient: Provides a stable connection with sufficient bandwidth for most small to medium-sized enterprises.

Considerations:

• Single Point of Failure: The setup relies on one BGP session; if this session fails, connectivity is lost until the issue is resolved.
• Limited Redundancy: May not meet the needs of businesses requiring high availability and continuous operation.

Overview:
In this configuration, two BGP sessions are established between our data center and the customer’s single router. This setup enhances redundancy, ensuring continuous internet connectivity even if one session experiences an issue.

Benefits:

• Redundancy: Increased reliability with two independent sessions.
• Failover Capability: If one session fails, the other maintains the connection, minimizing downtime.
• Better Load Balancing: Traffic can be distributed across both sessions for improved performance.

Considerations:

• Single Router Dependency: Although there are two BGP sessions, the single router remains a potential single point of failure.
• Complexity: Slightly more complex than a single session setup but offers improved reliability.

Overview:
This is the most robust option, with two BGP sessions established between our data center and two of the customer’s routers. This configuration offers the highest level of redundancy and load balancing, ensuring that internet connectivity remains unaffected by single points of failure.

Benefits:

• Maximum Redundancy: Eliminates single points of failure by using two routers.
• Enhanced Load Balancing: Distributes traffic effectively across multiple paths.
• High Availability: Ideal for mission-critical operations where uptime is paramount.

Considerations:

• Complexity and Cost: The most complex and potentially costly option due to the need for multiple routers and BGP sessions.
• Management: Requires careful management and configuration to maintain optimal performance and redundancy.
