No communication between the core switch and the router
eigrp is configured to distribute the routes between router and switch. The Router is set to use the wrong interface for the NAT overload. It is currently using the lan interface, the address that you need to use for the NAT is the WAN outside interface with the public IP. According to your configuration, the WAN interface is GigabitEthernet0/0/0. VLANs address scalability, security, and network management. In general, VLANs make it easier to design a network to support the goals of an. A device can be pinged from core switch ( router) but not the switch it's plugged into. It is. In this sample chapter from Switching, Routing, and Wireless Essentials Companion Guide (CCNAv7) for Cisco Networking Academy students, you will learn how to troubleshoot common inter-VLAN configuration issues. I'm sure I removed the correct VLANs. When I saved the configuration, everything stopped working and now we don't know what to do. -
Principle of Illuminated Identification Optical Cable
We developed local light injection and detection technology that enables us to identify the target fiber below an optical splitter. This technology uses the basic characteristic of optical fibers of an optical signal propagating through the optical fiber leaks at. Power communication networks serve as the core support for power grid dispatching, relay protection, distribution automation, and intelligent inspection. Optical cables such as OPGW and ADSS are widely deployed in substations, cable trenches, transmission towers, and underground pipe networks. The first course, Fiber Optics I –Theory, is an overview of the technology of fiber optic. There are two primary types of fiber optic cables: single-mode and multi-mode. - Single-mode fibers have a small core (about 8-10 microns in diameter) and are designed to carry light directly along the fiber with minimal reflections. -
