PROFILE

Simon Polack

Worked on the freifunk-berlin/bbb-configs repository to deliver robust network configuration and routing improvements over four months. Focused on automating and standardizing router and gateway management using Ansible, Shell, and YAML, the work included migrating routing protocols to Babel/BIRD, enhancing IPv4 and IPv6 mesh stability, and integrating BGP discovery for reduced manual maintenance. Upgrades to hardware and monitoring, such as Protectli device support and Naywatch integration, improved reliability and observability. Image build automation was expanded for deployment flexibility, while static IP configuration for uplinks increased network resilience. All changes were tracked with disciplined version control and clear commit history.

December 2024 highlights for freifunk-berlin/bbb-configs: Delivered Babel IPv4 routing enhancements with GRE cost alignment, mesh preference tuning, IPv4 metrics, and IPv4 route advertising, strengthening convergence and mesh reliability; refined static route control by increasing Bird's static default route preference. Implemented BGP discovery integration by installing and configuring bgpdisco to automate BGP route discovery, reducing manual routing maintenance. Hardware and monitoring modernization included migrating Saarbruecker gateway to Protectli VP6630 and enabling Protectli VPS6630 support, along with Naywatch for runtime monitoring, improving reliability and observability. Expanded image build automation to support build config overrides, additional serial ports, and appending board.d/02_network entries, enabling deployment-specific customization (with a subsequent revert to address a follow-on issue). Enhanced network policy and routing resilience through GRE route handling improvements, unconditional inbound_filtered traffic, firewall term ordering refinements, ICMP rate-limit adjustments, and an OLSR domain update to ff, contributing to more robust and predictable network behavior.
