What are the characteristics of routing protocols?

What are the characteristics of routing protocols?

Routing protocols can be compared based on the following characteristics: Speed of convergence: Speed of convergence defines how quickly the routers in the network topology share routing information and reach a state of consistent knowledge. The faster the convergence, the more preferable the protocol.

What are the characteristics of the Border Gateway Protocol?

The characteristics of BGP follow:

  • BGP is an exterior gateway protocol (EGP) used in routing in the Internet.
  • BGP is a path vector routing protocol suited for strategic routing policies.
  • It uses TCP port 179 to establish connections with neighbors.
  • BGPv4 implements CIDR.
  • eBGP is used for external neighbors.

What is IGP and EGP in networking?

An interior gateway protocol (IGP) is a routing protocol that is used to exchange routing information within an autonomous system (AS). In contrast, an Exterior Gateway Protocol (EGP) is for determining network reachability between autonomous systems and makes use of IGPs to resolve routes within an AS.

What are the characteristics of OSPF?

OSPF supports/provides/advantages –

  • Both IPv4 and IPv6 routed protocols.
  • Load balancing with equal-cost routes for the same destination.
  • VLSM and route summarization.
  • Unlimited hop counts.
  • Trigger updates for fast convergence.
  • A loop-free topology using SPF algorithm.
  • Run-on most routers.
  • Classless protocol.

What is IGP routing protocol?

An interior gateway protocol (IGP) is a dynamic route update protocol used between routers that run on TCP/IP hosts within a single autonomous system. The routers use this protocol to exchange information about IP routes.

What characteristics do routing protocols consider when determining the best path?

The best path is selected by a routing protocol based on the value or metric it uses to determine the distance to reach a network. A metric is the quantitative value used to measure the distance to a given network. The best path to a network is the path with the lowest metric.

What is IGP?

(1) (Interior Gateway Protocol) A broad category of routing protocols that support a single, confined geographic area such as a local area network (LAN). IGP was described in IETF RFC 1074 (1988). Common IGPs include the Routing Information Protocol (RIP) and the Open Shortest Path First (OSPF) protocol.

Which protocol is an EGP protocol?

Border Gateway Protocol (BGP)
Border Gateway Protocol (BGP) is the only Exterior Gateway Protocol (EGP) at the time.

What are two characteristics of OSPF choose two?

What are two characteristics of OSPF areas? (Choose two.)

  • Area 0 is called the backbone area.
  • All OSPF networks require the use of multiple areas.
  • OSPF areas create a three-layer hierarchical design.
  • All OSPF areas must be directly connected to Area 0.
  • Single area OSPF networks must be configured in Area 1.

What are the types of routing protocol?

7 types of routing protocols

  • Routing information protocol (RIP)
  • Interior gateway protocol (IGRP)
  • Enhanced interior gateway routing protocol (EIGRP)
  • Open shortest path first (OSPF)
  • Exterior Gateway Protocol (EGP)
  • Border gateway protocol (BGP)
  • Immediate system-to-immediate system (IS-IS)

What are the two categories of IGP protocols?

There are two types of IGP: distance vector routing and link state routing. Distance Vector Routing Protocol gives each router in the network information about its neighbors and the cost of reaching any node through these neighbors.

What is the difference between routing and routed protocols?

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 are IGP and EGP routing protocols?

Interior Gateway Protocols (IGP) are used for intra-autonomous system routing – routing inside an autonomous system. Exterior Gateway Protocols (EGP) are used for inter-autonomous system routing – routing between autonomous systems Characteristics of IGP and EGP Routing Protocols

What is IGP (interior gateway protocol)?

IGP is a protocol used in a company, organization, or school environment, that is, in an autonomous system (AS). IGP is called the interior because it is responsible for creating and maintaining routing information within the routing area.

What is the difference between an IGP and an autonomous system?

IGPs are used for routing within a routing domain, those networks within the control of a single organization. An autonomous system is commonly comprised of many individual networks belonging to companies, schools, and other institutions.

What is the difference between BGP and IGP?

BGP is typically used between ISPs and sometimes between a company and an ISP. BGP is not part of this course or CCNA; it is covered in CCNP. An interior gateway protocol (IGP) is a routing protocol that is used to exchange routing information within an autonomous system (AS).
