Upcoming Labs

While we’re working on new stuff, you can already enjoy two dozen labs. In case you’re curious about what’s coming next, here’s what we’re working on:

• Implement Anycast Services with BGP
• EBGP-Only Data Center Design
• Multihop EBGP peering in a high-availability firewall scenario
• Firewall-on-a-stick scenario with two VRFs in the directly attached router.

We have plenty of other ideas, including:

Basic BGP Setup

Advanced exercises:

• Configure BGP graceful restart

Controlling Inbound Traffic

• Use conditional route advertisements to select primary/backup links for the inbound traffic

BGP in Service Provider Networks

• Use a hierarchy of route reflectors
• Reduce routing instabilities with BGP route flap dampening
• Implement policy-based routing with BGP
• Remote-triggered black hole
• External bogon feed
• Centralized route collection service (like bgp.tools)

• Using RPKI for route validation (with Routinator as the source of RPKI information)

  See this LinkedIn post for more details.

Advanced Scenarios

• Peering across a low-end router using a default route

  See this blog post for more details.

• Use BIRD as a BGP route server

Use MPLS with BGP

• Use BGP Labeled Unicast to extend MPLS paths across multiple autonomous systems
