Implement redundant Ethernet links between switches to increase bandwidth and ensure no switch-over delay in case of link failure. Utilize link aggregation and spanning tree protocols for optimal network redundancy, faster link restoration, and improved bandwidth capacity. With a focus on minimizing switch loops and utilizing meshing for HP switches, achieve reliable and efficient network operations.
