Loop Prevention in BGP Routing

Loop Prevention in BGP Routing-compressed

The stability and optimal performance of networks running BGP (Border Gateway Protocol) rely heavily on preventing routing loops. Loops can lead to suboptimal routing, congestion, and instability. Understanding techniques to avoid loops is critical for effective BGP operations. Preventing loops should be a top priority for network administrators operating BGP networks. Routing loops can cause … Read more

CUSTOMER uses XYZ ISP. Assume that if in a case XYZ goes down or overtakes by another ISP like ABC above example is set for the understanding of the LOCAL AS feature. You see here CUSTOMER has 300 AS and XYZ has 200 AS. In the case of overtaking XYZ via ABC then we cannot … Read more

A Guide to Using BGP Communities for Network Control and Documentation


The Border Gateway Protocol (BGP) is the routing protocol that glues the internet together. BGP allows different autonomous systems (AS), such as Internet Service Providers, to exchange routing information with each other. This allows each AS to build a consistent view of the global internet routing table and calculate the best paths to deliver traffic. … Read more

What is BGP Authentication Detail Explained

What is BGP Authentication? BGP authentication is the process of verifying the authenticity of BGP routing information. This is done by ensuring that only authorized routers are allowed to exchange BGP routing information. BGP authentication can be used to prevent malicious actors from injecting false routing information into the BGP system. BGP authentication can be … Read more
