What is BGP and its types?
What is BGP and its types?
In BGP, the neighbor relationship is configured manually. BGP neighbors are also known as BGP peers or BGP speakers. There are two types of neighbor relationship: IBGP (Internal BGP): If all the routers are neighbors of each other and belong to the same autonomous number system, the routers are referred to as an IBGP.
What is BGP in simple terms?
“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.”
How many types of BGP are there?
In a network with route reflectors, there are three types of BGP routers: Route reflectors. Route reflector clients. Non-client peers.
Which protocol is used in BGP?
Transmission Control Protocol (TCP)
Because BGP runs over Transmission Control Protocol (TCP), it is compatible with the rest of the internet, which uses TCP for communications. TCP makes sure data packets get sent and delivered across networks.
What is the port number of BGP?
port 179
BGP peers are established by manual configuration between routing devices to create a TCP session on port 179.
What type of protocol is BGP?
Border Gateway Protocol (BGP) refers to a gateway protocol that enables the internet to exchange routing information between autonomous systems (AS). As networks interact with each other, they need a way to communicate.
Is BGP TCP or UDP?
TCP
BGP uses TCP port 179 to communicate with other routers. TCP allows for handling of fragmentation, sequencing, and reliability (acknowledgement and retransmission) of communication packets.
Why is BGP over TCP?
BGP uses TCP as its transport protocol. This eliminates the need to implement explicit update fragmentation, retransmission, acknowledgement, and sequencing.
