BGP Conditional Advertisement

BGP Conditional Advertisement

Conditional Advertisement in BGP: In the above example, we have to set R2 as a route reflector and the other two as clients R1 & R2. We have passed a loopback on every router. And above you can see that a link with 90MB is for ABC city and a 50MB link for XYZ city. … Read more

BGP Local Autonomous System

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

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

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
