Routing Basics
Network,Routers in a network discover remote networks in two ways Statically configured routes Dynamic routing protocols By default routers knows only the directly connected networks represented by “C” Static Routing Static route are mainly used when routing from a particular network to a stub network. Stub networks are the networks that can be accessed through…

Active Directory Replication
Network,The Active directory is a database. It designed to handle a large number of read and search operations and a smaller number of changes and updates. Active directory replication is to ensure that the information stored on all domain controllers within a domain synchronized. The domains and domain controllers are multiple communication paths connect them.…

Dynamic Routing
Network,Routing Information Protocols (RIP) RIP is using the algorithms known as “distance vector algorithms”. They are sometimes known as Ford-Fulkerson algorithms and the term Bellman-Ford is also used. It send the complete routing table out to all active interface every 30 second.RIP only uses hop count to determine the best way to a remote network.…

Basic rules for naming devices in the SAN
Network,The Storage Networking Industry Association (SNIA) defines the storage area network (SAN) as a network whose primary purpose is the transfer of data between computer systems and storage elements. A SAN is a specialized, high-speed network that attaches servers and storage devices. Use of descriptive naming conventions is one of the most important factors in…

IP Routing
Network,What is Routing? IP routing is the process of moving packets from one network to another network and delivering the packets to hosts. In another way Routing is used for taking a packet from one device and sending it through the network to another device on different networks. What is Routing Protocols and Routed Protocols?…

The FHRP (First-hop Redundancy Protocols)
Network,The Multilayer switches can act as IP gateway for connected hosts by providing gateway addresses at VLAN SVIs and Layer 3 physical interfaces. These switches can also participate in routing protocols ad a traditional routers does. Multi Layer switch will offer a means of preventing one switch (gateway) failure from isolating an entire VLAN. The…
