What is the purpose of the GLBP weight configuration?

The purpose of the GLBP (Gateway Load Balancing Protocol) weight configuration is to influence AVF (Active Virtual Forwarder) selection. GLBP uses a weight value assigned to each participating router to determine which one should handle the incoming traffic. The router with the highest weight becomes the Active Virtual Forwarder and is responsible for forwarding packets out of the virtual gateway IP address. By adjusting the weight, network administrators can control the distribution of loads among routers, ensuring that traffic is balanced according to the network design and the capabilities of each device.

The other options address different aspects of network configuration and GLBP functionalities but do not pertain specifically to the weight setting. For instance, determining the default gateway refers to the configuration of a device to know which IP address to use for outbound traffic. Adjusting the hello time involves setting how often a device sends hello packets in protocols to maintain adjacency but does not relate to the selection of the AVF. Setting a maximum traffic load is not a function of GLBP weight but would pertain to overall network traffic management and quality of service configurations.
