How many Active Virtual Forwarders (AVFs) can the AVG assign in GLBP?

The correct answer is that the Active Virtual Gateway (AVG) in Gateway Load Balancing Protocol (GLBP) can assign up to four Active Virtual Forwarders (AVFs). In GLBP, the AVG is responsible for managing the assignment of the AVFs, which participate in traffic forwarding.

By allowing up to four AVFs, GLBP increases load balancing capabilities across multiple routers, enhancing redundancy and optimizing resource utilization. This allows for efficient traffic distribution, which helps improve network performance and reliability by ensuring that if one AVF fails, others can continue to forward packets seamlessly.

Furthermore, it is worth noting that each AVF can handle traffic, which means that network efficiency and redundancy are maximized with this design, allowing for multiple routers to distribute the load effectively. This feature distinguishes GLBP from other gateway redundancy protocols, making it advantageous for environments that require high availability and load sharing.
