A company wants to create highly available datacenters. BGP will allow the company to continue to maintain an Internet presence at all sites in the event that a WAN circuit at one site goes down.
About BGP
BGP (Border Gateway Protocol) is a type of routing protocol that functions to exchange information between Autonomous Systems (AS). This BGP is a Dynamic Routing and on the proxy itself there are several kinds of dynamic routing features other than BGP such as OSPF and RIP. To exchange information, BGP utilizes the TCP protocol so that there is no need to use other types of protocols to handle fragmentation, retransmission, acknowledgment and sequencing.
Characteristics Of BGP
- Using distance vector routing algorithm.
- Distance vector routing algorithm periodically copies the routing table from router to router.
- Changes to the routing table are updated between interconnected routers when a topology change occurs.
- Used between ISPs with ISPs and clients.
- Used to route internet traffic between autonomous systems.
- BGP is Path Vector routing protocol. In the process of determining the best routes, it always refers to the best and selected path that it gets from other BGP routers.
- BGP routers establish and maintain peer-to-peer connections using port number 179.
- Inter-peer connections are maintained using periodic keepalive signals.
- The metrics (attributes) for determining the best route are complex and can be modified flexibly.
- BGP has its own routing table which usually contains the routing prefixes it receives from other BGP routers
