Developed RFC 8654-compliant extended BGP message sizing for the FRRouting/frr repository, enabling support for messages up to 65535 octets while maintaining strict 4096-octet limits for OPEN and KEEPALIVE types. Used C programming and network protocol implementation skills to centralize negotiation-time max_packet_size computation, ensuring capability state changes were accurately reflected during session setup. Enhanced robustness by enforcing per-type size checks on message receipt, addressing issues with late limit derivation and reducing the risk of session resets or stalls. This work improved interoperability with RFC 8654 peers and strengthened production stability for large BGP updates in complex network environments.

Jun 1, 2026June 2026 FRRouting/frr delivered RFC 8654-compliant BGP extended message sizing, enabling 65535-octet BGP messages with per-message-type receive limits and preserving 4096-octet limits for OPEN/KEEPALIVE. Implemented centralized negotiation-time max_packet_size computation and updated negotiation paths to reflect capability state changes, improving robustness across passive/active sessions. Enforced per-type size checks on receive to prevent oversized OPEN/KEEPALIVE, fixing root-cause issues where limits were derived too late. Key outcomes: improved interoperability with RFC 8654-capable peers, reduced risk of session resets and update-induced stalls with large messages, and stronger stability for large updates in production. Technologies/skills demonstrated: C-level protocol engineering, RFC-based BGP sizing (RFC 8654), negotiation state management, type-aware receive handling, and careful edge-case handling across bgp_open_capability, bgp_open_option_parse, and related components.
