Exploring the Functions of Routing Routing is the process that forwards data packets between networks or subnetworks using a Layer 3 device: a router or gateway. The routing process uses network routing tables, protocols, and algorithms to determine the most efficient path for forwarding the IP packet. Routers greatly expand the scalability of networks by terminating Layer 2 … [Read more...]
Network Layer Devices
Network Layer Devices The most common network device found at the Network layer is a router; however, Layer 3 switches may also be implemented to create a WAN. Both routers and Layer 3 switches can carry out these functions: Suppress broadcasts or multicasts Determine the best path for data transfer (routing) Strip down and add to Data Link layer frames Implement … [Read more...]
IPv6
IPv6 Objectives: Describe the technological requirements for running IPv6 in conjunction with IPv4 (including: protocols, dual stack, tunneling, etc.) Describe IPv6 addresses IPv6 is a workable IP version that was created in anticipation of the inevitable exhaustion of IPv4 addresses. Cisco routers are capable of routing IPv4 and IPv6 traffic in the event that … [Read more...]
