Internet Peering Between Autonomous Systems (ASNs) or BGP Peering is a process of exchanging routing information between two independent networks. This type of peering is commonly used by ISPs to exchange traffic and provide better access to the Internet. In addition, many businesses and organizations use the same technology to connect their networks with other ASNs to increase their network’s reachability and performance.

In order to establish an Internet peering link between two ASNs, both networks must have a BGP router with a peering session configured. The peering session will allow the two networks to exchange routing information, such as the networks’ IP prefixes, which are necessary to establish a peering link. Once the session is established, the networks will be able to communicate and exchange data with each other.

The main benefit of peering is improved performance and access to the Internet. Peering links are often faster and more reliable than traditional methods of connecting to the Internet, such as buying transit from an ISP. In addition, peering allows organizations to connect to multiple ASNs at once, allowing them to access more of the Internet than they would be able to with a single connection.

While peering is a great way to improve access to the Internet, it is important to note that it is not without its drawbacks. Peering agreements can be complicated and require both parties to agree on certain terms and conditions. In addition, peering is not always available everywhere and some networks may not be able to connect to each other due to incompatibilities between their ASNs.

In summary, Internet peering between autonomous systems (ASNs) or BGP peering is a process of exchanging routing information between two independent networks. This type of peering is often used by ISPs and businesses to improve the performance and access to the Internet. Peering provides many benefits, including increased speed and reliability, but it also has some drawbacks, such as the potential for incompatibilities and the need to agree on certain terms and conditions.

Key Points:
• Internet peering between autonomous systems (ASNs) or BGP peering is a process of exchanging routing information between two independent networks.
• Peering links are often faster and more reliable than traditional methods of connecting to the Internet, such as buying transit from an ISP.
• Peering agreements can be complicated and require both parties to agree on certain terms and conditions.
• In addition, peering is not always available everywhere and some networks may not be able to connect to each other due to incompatibilities between their ASNs.

A follow up webinar with a bit more depth on BGP and peering.

An introduction to Peering between autonomous systems covers the following topics:

– Structure of the Internet
– Autonomous Systems
– Internet Routing Registries
– Peering versus transit
– Simple IX architecture
– Public versus private peering
– The LINX route servers
– The LINX route collector
– RPKI

BGP is the routing protocol of the Internet and the one used between our member networks here at LINX. This training is in partnership Systems & Network Training with trainer Rob Minshall.
