BGP Routing Policies

These lab exercises will help you master the essential tools you can use in BGP routing policies. You will also be able to practice creating more complex routing policies.

The labs are grouped into three sections:

  • Filtering BGP updates
  • Adjusting outgoing traffic flow
  • Influencing incoming traffic flow

Filtering BGP Updates

The first thing you should do when you use BGP to connect to the public Internet is limit the information you advertise to your neighbors to the prefixes you own. These labs will help you get there:

Adjusting Outgoing (Egress) Traffic Flow

It’s relatively easy to change how traffic leaves your network (autonomous system) – you have to modify the BGP- and routing tables on your routers. These labs – ranging from simple one-router scenarios to complex network-wide policies – will help you master the BGP tools you can use to get the job done:

Once you master the basics, you’ll be ready for more complex scenarios:

Influencing Incoming (Ingress) Traffic Flow

Trying to persuade neighboring autonomous systems to change how they send you the traffic is much more complicated than changing the routing in your network. While there’s no definitive one-size-fits-all solution, you will find these tools indispensable:

More Complex Routing Policies

You use these labs to practice how to use a combination of BGP attributes and routing policy tools to build more complex routing policies:
