Dynamic routing protocols can be classified in various ways. These can be classified into three groups: 1. IGP and BGP protocols 2. Distance vector and link state protocols 3. Classful and Classless protocols The first classification is based upon protocol to be used within our network or between our network and another network. In the [...]
All routing protocols can also be classified- 1. Classful routing protocols These protocols do not send subnet mask information in their routing updates.Teh first routing protocol RIP is classful protocol. It was introduced when network addresses were allocated based on classes-classA,classB and class C.RIP need not to include the subnet mask in the routing updates [...]
-EIGRP is Enhanced Interior Gateway Routing Protocol. -EIGRP known as hybrid protocol because it has characteristic of both distance vector routing protocol and link state routing protocol. -EIGRP is based on Bellman-Ford algorithm. -Administrative distance of EIGRP is 90 for internal route and 170 for external route and 5 for the summary route. -Metric of [...]
Every router uses the operation system and the OS used in router is known as Internetwork operation System (IOS).Similar the operating system of the computer Cisco IOS is responsible to manage the hardware and software resources of the router. It is a multitasking operating system that is integrated with routing, switching, and internetworking and telecommunications [...]
Bridge operates in both the physical layer and the data link layer of the OSI model. Bridges can divide a large network in to smaller segments. Bridge connects one local area network to another local area network and uses the same protocol. The Bridge looks each and every message and passes it to the other [...]
Distance vector protocol, RIP sends the periodic updates to maintain the routing table. Unlike the RIP, EIGRP does not send the periodic updates, it sends the bounded updates means EIGRP send updates when the topology changes or the metric for that route is change. When any router to be add or removed, EIGRP send an [...]
The administrative distance provides preference to the path. When the routing process determine which route to be used when forwarding a packet, before it router first determine which route to be include in the routing table. It can be happen when a router learn a route to a remote network from more than one routing [...]
Similar to the computer, a router uses a process to boot. It includes testing the hardware, loading the IOS, performing the configuration commands in the startup configuration file. The process is following: Post-It is process used to test the router hardware. When the router powered on, post operation is starts. After the post has been [...]
The OSI Model describes the functionalities of the data link layer that are-addressing, framing and accessing the media from the physical layer standard. Ethernet standard define both the layer 2(Data link layer) protocol and the layer 1 (Physical layer) technologies. The Ethernet is the LAN product and described by the IEEE standard. The standard for [...]
Network is a group of connected two or more systems sharing the resources and communicate to each other by the means of shard communication link. A Network requires two or more individual system with something to share and the system must be connecting through the communication media. All the system must follow the physical rules [...]
