What is BGP ?

Border Gateway Protcol (BGP) forms the core of the internet traffic as every computer (router, node, switches -- anything and everything that uses TCP) relies on BGP to find the routes. On the 4 layer TCP/IP model, this is in the Layer4. The routes are often manually configured.

From a real world perspective, a BGP route can be a localite who knows the routes of the area. A visitor the area will trust the localite and then fall into trouble.

What is BGP Poisoning ?

poisoning or Hijacking happens when some one publishes a wrong route. Since many time routes are configured manually, this could be unintentional too.
