Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. [2] BGP is classified as a path-vector routing protocol, [3] and it makes routing decisions based on paths, network policies, or rule-sets configured by a network ...
Multiprotocol Extensions for BGP (MBGP or MP-BGP), sometimes referred to as Multiprotocol BGP or Multicast BGP and defined in IETF RFC 4760, [1] is an extension to Border Gateway Protocol (BGP) that allows different types of addresses (known as address families) to be distributed in parallel.

For example, on Cisco routers, routes issued by the Open Shortest Path First routing protocol have a lower default administrative distance than routes issued by the Routing Information Protocol. This is because, by default on Cisco routers, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120.
Route table showing internet BGP routes . In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.
Normally the Border Gateway Protocol (BGP) used by the provider's routers only looks at the four-octet IP address, but the BGP Multiprotocol Extensions allow BGP to view the entire 12-octet VPN-IPv4 address, and carry routes from multiple "address families". If the route distinguisher Administrator subfield and the Assigned Number subfield of a ...
It is Core-Based Tree, selecting one router in the network as the root and transmitting information through the root router. Maximum delay in the tree is longer than SBT(Source-based tree), The core router manages all the information, and the remaining routers manage the direction of the core and the multicast information requested by the current neighboring router. it has a Good Scalability ...
The concept of BGP hijacking involves identifying an Internet Service Provider (ISP) that does not filter advertisements, whether intentionally or unintentionally, or identifying an ISP with vulnerable internal or ISP-to-ISP BGP sessions susceptible to a man-in-the-middle attack. Once identified, an attacker can potentially advertise any prefix ...
