understood the working concept of Cluster ID when having multiple RR's with multiple clusters, but Could you pl provide the practical scenario where there is a chance of loop and how cluster ID will help in avoiding the loops..


Thanks,

Cluster ID in avoid the LOOP

Hi Rajesh,

You can build you own with GNS3, simply build a kind of triangle.

You just need to memorize that the goal to reach is to reflect back a route to its originator.

Imagine & draw an AS with 3 Clusters of 2 RRs each interconnected, each of them by well placed links.

Inject some prefix in BGP in a specific Cluster and look the result.

Mother of learning is practicing good luck in your study!
