How BGP Works with JunOS
BGP or Border Gateway Protocol is a routing methodology that is aimed to optimize the transit times of data packets traversing the public internet. BGP is designed to leverage communication with Autonomous Systems of AS that act as network hubs. A good way to think of an autonomous system is as a set of internal IP addresses for an internet network that also manages routing tables that give information about their distance to other Autonomous Systems. By leveraging this routing table of Autonomous Systems, the BGP protocol can optimize the transmission of data packets by selecting the shortest path between connected Autonomous Systems.
BGP is a major foundation of the Junos Operating System supporting BGP version 4. This iteration of BGP 4 provides additional support for classless interdomain Routing, a primary routing mechanism in Junos environments. This unique routing protocol shrinks the size of the routing table, minimizing table search times and in doing so, minimizes the packet transmission times.
