The First Hop Redundancy Protocols (FHRPs) are meant to provide redundancy for your routing devices. What other redundancies do you think you should implement if you were looking to make your network resilient to failure? short summary

Answer 1

To enhance network resilience beyond First Hop Redundancy Protocols (FHRPs), consider implementing the following redundancies:

1. Link Redundancy: Utilize multiple physical links between devices to ensure connectivity in case one link fails. Technologies like Link Aggregation Control Protocol (LACP) can be useful.

2. Device Redundancy: Deploy redundant hardware (e.g., routers, switches, firewalls) to prevent single points of failure. Use Virtual Router Redundancy Protocol (VRRP) or Gateway Load Balancing Protocol (GLBP) alongside FHRPs.

3. Path Redundancy: Implement multiple routing paths, using protocols like Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP) to dynamically reroute traffic in case of a path failure.

4. Power Redundancy: Ensure that critical network devices have dual power supplies or Uninterruptible Power Supplies (UPS) to avoid outages due to power failure.

5. Data Redundancy and Backup: Regularly back up critical configurations and data, implementing redundant data storage solutions like RAID, to prevent data loss.

6. Geographic Redundancy: Establish secondary data center locations or disaster recovery sites that can take over in the event of a primary site failure.

7. Load Balancing: Distribute traffic across multiple servers or devices to reduce the risk of overload and improve overall performance.

These measures collectively create a robust and fault-tolerant network infrastructure, enhancing uptime and reliability.
