When a router disseminates erroneous BGP routing information, whether intentionally or accidentally, it is defined by the Internet Engineering Task Force (IETF) in RFC 7908 as a "route leak." These leaks are characterized as "the dissemination of routing announcements beyond their intended scope.
The AS 7007 incident was a major disruption of the Internet on April 25, 1997, that started with a router operated by autonomous system 7007 (MAI Network Services, although sometimes incorrectly attributed to the Florida Internet Exchange [1]) accidentally leaking a substantial part of its entire routing table to the Internet, creating a routing black hole.
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 administrator. BGP used for routing within an autonomous system is called Interior Border Gateway Protocol (iBGP).
A Border Gateway Protocol (BGP) routing problem played a role in the outage. [ 28 ] [ 29 ] [ 30 ] Public data from CloudFlare showed a spike in BGP route announcements from the Optus network around the time the outage occurred — over 940,000 announcements in an hour from a node that normally makes less than 3,000 announcements per hour ...
RFC 2545 (Use of BGP-4 Multiprotocol Extensions for IPv6 Inter-Domain Routing) RFC 1997 (BGP Communities Attribute) RFC 2796 (BGP Route Reflection - An Alternative to Full Mesh IBGP) RFC 3065 (Autonomous System Confederations for BGP) RFC 2439 (BGP Route Flap Damping) RFC 4893 (BGP Support for Four-octet AS Number Space)
Border Gateway Protocol (BGP) is used to route traffic on the internet. BGP hijacking is a form of cyber-attack where an attacker alters the routing information in BGP, causing internet traffic to be directed to the wrong place.
Major DNS resolvers returning "SERVFAIL" status for Facebook.com. Security experts identified the problem as a Border Gateway Protocol (BGP) withdrawal of the IP address prefixes in which Facebook's Domain Name System (DNS) servers were hosted, making it impossible for users to resolve Facebook and related domain names, and reach services.
In Internet routing, the default-free zone (DFZ) is the collection of all Internet autonomous systems (AS) that do not require a default route to route a packet to any destination. Conceptually, DFZ routers have a "complete" Border Gateway Protocol table, sometimes referred to as the Internet routing table, global routing table or global BGP table.
