Final answer:
GLBP (Gateway Load Balancing Protocol) is the technology that seeks to automatically distribute the load on redundant default gateways. It allows multiple routers to share the same virtual IP address, enabling load balancing and redundancy.
Step-by-step explanation:
The technology that seeks to automatically distribute the load on redundant default gateways is GLBP (Gateway Load Balancing Protocol). GLBP is a Cisco proprietary protocol that allows multiple routers to share the same virtual IP address, enabling load balancing and redundancy. When a client sends a request, GLBP selects one router as the active gateway and the other routers as backup gateways. This ensures that network traffic is evenly distributed across all available paths, improving performance and reliability.
