At which layer of the OSI model does a standard Router primarily operate, and what is the specific name of the Protocol Data Unit (PDU) at this layer? A router has four contiguous /24 routing table entries: 10.1.0.0/24, 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24. If you summarize (supernet) these into a single route,what will be the new CIDR notation?
