Step 3. Path Determination and Switching Function Exercise Can you describe the exact details of what happens to a packet at Layer 2 and Layer 3 as it travels from source to destination. These transition cables support the same five serial standards and are available in either data terminal equipment DTE or data communications equipment DCE configurations. Becoming a member and registering is free, and you then gain access to exclusive deals on other resources from Cisco Press.
What parent network will automatically be included in the routing andd when the three subnets are configured on Router1. The last part of this line displays the amount of DRAM. What header address information does a router explorztion in the information it receives from an attached Ethernet interface before information is transmitted out another interface. By reviewing the routing tables in the figure, we can verify that all directly connected networks are installed for routing.

Much more than documents.
In the figure, R1 examines the destination IP address of the packet. Which of the following matches a router component with its function. New route information must be learned from multiple sources to be accepted. Without the sacrifices you made during the project, this work would not have come to fruition.
Using bytes. The end of each chapter of this Companion Guide indicates with icons what labs, activities, the objectives reference the core concepts covered in the chapter. ObjectivesListed at the beginning of each chapter? Task Load the start.Can you describe the basic structure of a routing table. Building the Routing Table The primary function of a router is to forward packets toward their destination network, routing protocols consider neighbors to be devices that share the same network address space. At Layer 3, the destination IP address of the packet. A key exploratiln of the switching function is to encapsulate packets in the appropriate data-link frame type for the outgoing data link.
Although not shown in the example, R2 is also a member of two networks: A technician needs to add a new loopback interface to test routing functionality and network design. Debug commands should be used protoccols caution on production net- works because they can affect the performance of the device. Which summarization will work for all the subnets.
