Which is exterior gateway protocol?
Exterior Gateway Protocol (EGP) is the mechanism that allows the exterior gateway of an autonomous system to share routing information with exterior gateways on other autonomous systems.
What is the most commonly used exterior gateway protocol?
Border gateway protocol (BGP)
Border gateway protocol (BGP) is the most popular exterior gateway protocol (EGP) in use on the Internet today.
Which of the following is an example of an exterior gateway protocol?
From all these options Border Gateway Protocol(BGP) is answer.
Is BGP an exterior gateway protocol?
“Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.”
What is EGP and BGP?
The Border Gateway Protocol (BGP) is one of a family of IP Routing protocols, and is an Exterior Gateway Protocol (EGP) designed to distribute routing information between ASs. EGPs are all vector routing protocols.
What is IGP and EGP?
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 is IGP and EGP protocol?
Why OSPF is not used in exterior routing?
This full view does come with some downsides: greater memory and CPU resources being used. That’s why OSPF is usually used for internal, rather than external, routing. Being an IGP, the overhead of being a link-state protocol is minimized due to the smaller topology.
What is an example of an EGP?
Examples of EGPs include: Border Gateway Protocol (BGP) Exterior Gateway Protocol (EGP) The ISO’s InterDomain Routing Protocol (IDRP)
What is OSPF full form?
Open Shortest Path First (OSPF) is a link-state routing protocol that was developed for IP networks and is based on the Shortest Path First (SPF) algorithm. OSPF is an Interior Gateway Protocol (IGP).
What is external BGP?
External Border Gateway Protocol (EBGP) is a Border Gateway Protocol (BGP) extension that is used for communication between distinct autonomous systems (AS). EBGP enables network connections between autonomous systems and autonomous systems implemented with BGP.
