IPv4 Routing Basic Data Communication Quiz by Ravinder Nath Rajotiya - November 14, 20190 Introduction An entreprize network is an instance of an autonomous systems. An autonomous system or AS, as it is also commonly known, is a connected group of one or more IP prefixes run by one or more network operators which has a SINGLE and CLEARLY DEFINED routing policy. In the evolution phase of networking, the AS considered the existence of a single routing protocol, however as networks have evolved, it is possible to support multiple routing protocols that inter-operate through the injection of routes from one protocol to another. Routing Policy : A routing policy can be understood to be a set of rules that determine how traffic is managed within an autonomous system, to which a single, or multiple operator(s) must adhere
Versatile Routing Platform(VRP) Data Communication Quiz by Ravinder Nath Rajotiya - November 14, 2019November 11, 20200 Versatile Routing Platform(VRP) It is a Command Line Interface which is used for configuration, management and monitoring of devices. It is based on a standardized and hierarchical command line system. Huawei devices use eNSP software for this purpose. The command line interface The command line interface has four command views: They are: User View: The initial command view of VRP is the User View, which operates as an observation command view for observing parameter statuses and general statistical information. System View: This view is used for configuring the huawei products. For application of changes to system parameters, users must enter the System View Interface View: Protocol View: lThe example demonstrates a selection of common system defined shortcut keys that are widely used to simplify the navigation process within the VRP
Single Switched Network Data Communication Quiz by Ravinder Nath Rajotiya - November 14, 2019November 14, 20190 Single Switched Network The shift is from a single collision domain towards the multiple collision domain which is possible because of evolution of network technology such as switch and the 100 base-T form of media. This has has isolated as transmission and reception on two separate wires. No collision hence no need for CSMA/CD. There is a requirement of multi-port switches. This brings the capability for increased port density to enable the connection of a greater number of end system devices within a single local area network Each end system or host within a local area network is required to be connected as part of the same IP network in order for communication to be facilitated at the network layer. The IP address however is
Rapid Spanning Tree Protocol Data Communication Quiz by Ravinder Nath Rajotiya - November 14, 2019November 14, 20190 Rapid Spanning Tree Protocol RSTP was introduced to overcome the limitations of the spanning tree protocol (STP). Advantage of STP: Though STP ensures a loop-free network. Problem with STP: With increased topology changes, STP slows down the network topology convergence speed, leading to service deterioration causing regular interruption. RSTP employs a proposal and agreement process which allows for immediate negotiation of links to take place, effectively removing the time taken for convergence based timers to expire before spanning tree convergence can occur. The proposal and agreement process tends to follow a cascading effect from the point of the root bridge through the switching network, as each downstream switch begins to learn of the true root bridge and the path via which the root bridge can be
Spanning Tree Protocol Data Communication Quiz by Ravinder Nath Rajotiya - November 13, 2019November 13, 20190 Spanning Tree Protocol As a enterprise networks expands it require more number of switches. Switches are a point-to-point interconnections via end systems are able to forward frames to destinations located via other switches within the broadcast domain. The failure of one switch or its link results in the immediate isolation of the downstream connectivity. In order to resolve this issue, redundancy is highly recommended within any switching network. Redundant links are therefore generally used on an Ethernet switching network to provide link backup and enhance network reliability. The use of redundant links, however, may produce loops that cause the communication quality to drastically deteriorate, and major interruptions to the communication service to occur. One of the initial effects of redundant switching loops comes
