Modern IBGP Design with AddPath and ORR
Nicola Modena created an interesting presentation describing IBGP designs using BGP Additional Paths and Optimal Route Reflection functionality
Hope you’ll enjoy the presentation as much as I did… and make sure you understand potential circular dependencies you might be introducing when running a route reflector as a virtual machine.

The state of cloud-native security 2022 – Tigera’s new market report
We are excited to announce the publication of our first State of Cloud-Native Security market report! The report compiles survey results from more than 300 security and IT professionals worldwide (all of whom have direct container responsibilities), and explores organizations’ needs and challenges when it comes to containers and cloud-native applications, specifically in the areas of security, observability, and compliance.
Report highlights
Our survey results showcase the rise in cloud-native development, while identifying barriers and areas where organizations need support on their cloud-native journey. Some of the report’s key findings include:
- Cloud-native applications gain momentum but present security, compliance, and observability issues.
- While our survey found that 75% of companies are focusing development on cloud-native applications, the increased development (and deployment) also creates the need for more advanced observability and security capabilities.
- Containers require security solutions for runtime, access, and networking.
- 98% of organizations need container security, with runtime security topping the list.
- Cloud-native and container compliance requirements are driving delays and challenges.
- 95% of organizations report they have compliance requirements for cloud-native applications, with 84% stating that meeting these compliance requirements is challenging.
Why read the report?
The report gives organizations a chance to benchmark themselves against the findings, Continue reading
BGP Policy (Part 6)
At the most basic level, there are only three BGP policies: pushing traffic through a specific exit point; pulling traffic through a specific entry point; preventing a remote AS (more than one AS hop away) from transiting your AS to reach a specific destination. In this series I’m going to discuss different reasons for these kinds of policies, and different ways to implement them in interdomain BGP.
In this post I’m going to cover local preference via communities, longer prefix match, and conditional advertisement from the perspective of AS65001 in the following network—
Communities an Local Preference
As noted above, MED is the tool “designed into” BGP for selecting an entrance point into the local AS for specific reachable destinations. MED is not very effective, however, because a route’s preference will always win over MED, and because it is not carried between autonomous systems.
Some operators provide an alternate for MED in the form of communities that set a route’s preference within the AS. For instance, assume 100::/64 is geographically closer to the [65001,65003] link than either of the [65001,65002] links, so AS65001 would prefer traffic destined to 100::/64 enter through AS65003.
In this case, AS65001 can advertise 100::/64 with Continue reading

Heavy Strategy Podcast – The Great Realisation Not Great Resignation
Heavy Strategy is about IT strategy. My co-host Johna Till-Johnson is the CEO/founder of Nemertes Research with a lot of strategy experience that combines with her technical background. The great thing is that Johna is willing to strongly debate topics. We go “head to head” and disagree to discuss. Its enjoyable and the feedback has been […]
