What happens when a host in a dual ring topology goes down?

In a dual ring topology, if a host goes down, the network can still function normally due to the presence of two separate rings. The data can be rerouted through the operational ring, maintaining connectivity among the remaining hosts. However, the failure of a host may lead to increased latency or reduced bandwidth, depending on the network's design and traffic load. Ultimately, redundancy in the dual ring structure helps mitigate the impact of a single host failure.
