BGP Interview Questions and Answers for Freshers

Border Gateway Protocol (BGP) is a protocol that allows two networks to communicate with one other. BGP is a standardized outside gateway protocol that allows autonomous systems (AS) on the Internet to share routing and reachability information. A route vector protocol is what the protocol is called. The Border Gateway Protocol is engaged in fundamental routing choices and determines routing decisions depending on pathways, network regulations, or rule sets a network administrator provides.

Within an autonomous system, BGP may be utilized for routing. Interior Border Gateway Protocol, often known as Internal BGP or iBGP, is used in this application. The protocols Internet implementation, on the other hand, is known as Exterior Border Gateway Protocol, External BGP, or eBGP.

What distinguishes the Border Gateway Protocol (BGP) from other protocols?

  • The Border Gateway Protocols primary purpose is to allow communication between two autonomous systems.
  • The Border Gateway Protocol supports the Next-Hop Paradigm.
  • There is cooperation among various BGP speakers inside the autonomous system.
  • Information about the path: BGP advertising includes route information and the accessible destination and next destination pair.
  • Numerous characteristics are employed in the BGP routing-decision process.
  • BGP is used to transmit external neighbours amongst autonomous systems.
  • BGP is used by internal neighbours inside the same autonomous system.
  • It uses weight to change the outbound traffic routing from a single locally configured router.
  • The Border Gateway Protocol can apply policies set up by the administrator. For example, a BGP router can be configured to distinguish between routes known within the autonomous system and outes known from outside the autonomous system.
  • TCP (Transmission Control Protocol) and BGP (Border Gateway Protocol) are used.
  • The Border Gateway Protocol (BGP) is a protocol that helps networks conserve bandwidth.
  • BGP supports Classless Inter-Domain Routing (CIDR).
  • BGP also helps with security.

    1. Your BGP router must insert your IP prefix into its BGP routing table.
    2. The IP prefix must be advertised to its BGP neighbors.
    3. The IP prefix must be propagated throughout the internet.
