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.
Border Gateway Protocol Security (BGPsec) is a security extension of the Border Gateway Protocol defined in RFC 8205, published in September 2017. BGPsec provides to receivers of valid BGPsec UPDATE messages cryptographic verification of the routes they advertise. [1] BGPsec replaces the BGP AS_PATH attribute with a new BGPsec_Path attribute. [2]
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
BGP is the standard routing protocol used to exchange information about IP routing between autonomous systems. Each AS uses BGP to advertise prefixes that it can deliver traffic to. For example, if the network prefix 192.0.2.0 / 24 is inside AS 64496, then that AS will advertise to its provider(s) and/or peer(s) that it can deliver any traffic ...
There are two standardized protocols for managing MPLS paths: the Label Distribution Protocol (LDP) and RSVP-TE, an extension of the Resource Reservation Protocol (RSVP) for traffic engineering. [24] [25] Furthermore, there exist extensions of the Border Gateway Protocol (BGP) that can be used to manage an MPLS path. [14] [26] [27]
Anycast is a network addressing and routing methodology in which a single IP address is shared by devices (generally servers) in multiple locations. Routers direct packets addressed to this destination to the location nearest the sender, using their normal decision-making algorithms, typically the lowest number of BGP network hops.
Internet traffic exchange between two participants on an IXP is facilitated by Border Gateway Protocol (BGP) routing configurations between them. They choose to announce routes via the peering relationship – either routes to their own addresses or routes to addresses of other ISPs that they connect to, possibly via other mechanisms.
