The Border Gateway Protocol (BGP) is a fundamental part of sending data over the internet. In this case, you want to be sure that your routes are correctly advertised and reachable following the change. Advertising routes that cannot deliver traffic is known as “blackholing.” What Can Go Wrong? BGP Route Misconfigurations.

The traffic inside VPC is forwarded to a Direct Connect Gateway (DXG). Vendor’s data centers have private links to their own routers which are set up in AWS Direct Connect Locations. Direct Connect Location: a high-speed AWS network traffic exchange center that contains both AWS Direct Connect routers and vendor’s routers.

Designed before the dawn of the commercial Internet, the Border Gateway Protocol (BGP) is a policy-based routing protocol that has long been an established part of the Internet infrastructure. An internal routing scheme so that every router in a given AS knows how to get to every other router and destination within the same AS.

Border Gateway Protocol (more commonly known as BGP ) is the routing protocol that makes the internet work. It is the language spoken by routers to determine how packets can be sent from one router to another to reach their final destination. In this case it was due to more specific prefixes that should not have been advertised.

In this blog, we will explore what static routes are, how they differ from dynamic routes, and how to configure them on routers like Cisco devices. This characteristic makes them efficient for routers with limited processing capabilities. A static route is a manually configured path in a routing table.

More Basics: Advertising, Homing, and Cardinal Sins. Advertising Routes. As discussed in Part 1, the path traveled by traffic is referred to as a route, and BGP is the protocol by which one “advertises” to the Internet the routes available to get traffic to your AS. For example, if you advertise 192.204.4.0/24

As the internet grew, the pool of available IPv4 dwindled until a private market emerged to facilitate the sale of what was no longer just a simple router setting, but an increasingly precious commodity. Over the years, only a portion of that address space was ever utilized (i.e. announced by the DoD on the internet).
