What is the difference between interior and exterior routing?
Interior Gateway Protocol (IGP) is a Routing Protocol which is used to find network path information within an Autonomous System. Exterior Gateway Protocol (EGP) is a Routing Protocol which is used to find network path information between different Autonomous Systems.
What is the different between routed and routing protocols please explain?
You must know the difference between a “ routed ” protocol and a “ routing protocol ”. A routed protocol is a protocol by which data can be routed . A routing protocol , on the other hand, is only used between routers. Its purpose is to help routers building and maintain routing tables.
What does an interior routing protocol do?
An interior gateway protocol (IGP) is a type of protocol used for exchanging routing information between gateways (commonly routers) within an autonomous system (for example, a system of corporate local area networks). This routing information can then be used to route network-layer protocols like IP.
What is the main difference between the OSPF and IS IS routing protocols?
What are the main differences between the OSPF and IS-IS routing protocols ? OSPF requires an area 0, while IS-IS does not. OSPF is a classful protocol , while IS-IS is a classless protocol . OSPF is a link state protocol , while IS-IS is not.
What is ISIS routing protocol?
Intermediate System to Intermediate System (IS-IS, also written ISIS ) is a routing protocol designed to move information efficiently within a computer network, a group of physically connected computers or similar devices. It accomplishes this by determining the best route for data through a Packet switching network.
Why is it difficult for routing loops to occur in networks that use link state routing?
Why is it difficult for routing loops to occur in networks that use link – state routing ? Each router builds a simple view of the network based on hop count. Each router builds a complete and synchronized view of the network . Routers use hold-down timers to prevent routing loops .
What are routing protocols used for?
A routed protocol is used to deliver application traffic. It provides appropriate addressing information in its internet layer or network layer to allow a packet to be forwarded from one network to another. Examples of routed protocols are the Internet Protocol (IP) and Internetwork Packet Exchange (IPX).
Is IPX a routing protocol?
IPX is a Novell NetWare protocol used for routing packets from one network node to another throughout an internetwork. Internetwork Packet Exchange ( IPX ) is a network layer protocol and provides connectionless datagram services for Ethernet, Token Ring, and other common data-link layer protocols .
What are the dynamic routing protocols?
Dynamic routing uses multiple algorithms and protocols . The most popular are Routing Information Protocol (RIP) and Open Shortest Path First (OSPF). Dynamic routing protocols allow routers to share information about the network with other routers to allow them to select the best path to reach a destination.
Which of the following is an interior routing protocol?
The Routing Information Protocol (RIP ) is the interior protocol most commonly used on UNIX systems. RIP is included as part of the UNIX software delivered with most systems. It is adequate for local area networks and is simple to configure. RIP selects the route with the lowest “hop count” (metric) as the best route.
What is the most used routing protocol?
Open Shortest Path First (OSPF)
Which of the following is a routing protocol?
The key is to think of routing protocols as distance vector or link state protocols, IGP or EGP protocols, and classful or classless protocols. These are the overarching categories that common routing protocols like RIP , IGRP , OSPF , and BGP fall within.
IS IS routing protocol Cisco?
IS-IS is an IGP, link-state routing protocol , similar to OSPF. It forms neighbor adjacencies, has areas, exchanges link-state packets, builds a link-state database and runs the Dijkstra SPF algorithm to find the best path to each destination, which is installed in the routing table.
What information does the next hop entry?
Routers use metric values to identify the distance, or cost, to a destination network. What information does the ‘next hop ‘ entry in a routing table identify? The first router in the path to the destination network.
Which of the following best describes OSPF?
Which of the following best describes OSPF ? OSPF is a classless link-state routing protocol. Network traffic due to sharing routing information is less than with the distance vector method. Convergence is faster than with the distance vector method.
