What is Inter-Domain Routing protocol?

Inter-domain routing is data flow control and interaction between Primary Domain Controller (PDC) computers. This type of computer uses various computer protocols and services to operate. It is most commonly used to multicast between internet domains.

Is OSPF an Inter-Domain Routing protocol?

OSPF is a link-state intra-domain routing protocol used in IP networks, which calls for the sending of Link State Advertisements (LSAs) to all other routers within the same hierarchical area.

Is an example for Inter-Domain Routing?

As explained earlier, the Internet is composed of more than 45,000 different networks [1] called domains . Each domain is composed of a group of routers and hosts that are managed by the same organisation. Example domains include belnet, sprint, level3, geant, abilene, cisco or google …

Is BGP Inter-domain?

The Internet uses a single interdomain routing protocol : the Border Gateway Protocol (BGP). The current version of BGP is defined in RFC 4271. BGP differs from the intradomain routing protocols that we have already discussed in several ways. First, BGP is a path-vector protocol.

What is difference between IntraDomain and InterDomain routing?

InterDomain Routing as name suggests is the protocol in which Routing algorithm works within and between domains. On other hand IntraDomain as name suggests is a protocol in which Routing algorithm works only within the domains.

What is OSPF and how it works?

OSPF is an interior gateway protocol (IGP) for routing Internet Protocol (IP) packets within a single routing domain, such as an autonomous system. It gathers link state information from available routers and constructs a topology map of the network.

How does CIDR benefit the Internet?

The initial goal of CIDR was to slow the increase of routing tables on routers across the internet and decrease the rapid exhaustion of IPv4 addresses. As a result, the number of available internet addresses has greatly increased.

Why is BGP so different from OSPF?

The main difference between OSPF and BGP is that OSPF is an intra-domain routing protocol using link state routing, and the routing operation is performed inside an autonomous system while BGP is the inter-domain routing protocol that uses path vector routing, with the routing operations performed between two …

What are the BGP states?

In order to make decisions in its operations with peers, a BGP peer uses a simple finite state machine (FSM) that consists of six states: Idle; Connect; Active; OpenSent; OpenConfirm; and Established.

Is OSPF is interdomain or Intradomain?

In InterDomain Routing Interior-gateway protocols such as RIP(resource information protocol) and OSPF(open shortest path first) are being used. While On other Exterior-gateway protocols such as BGP(Border Gateway Protocol) are being get used in case of IntraDomain Routing.
