Dec 1, 2025December 2025: Delivered targeted FRR fixes in LabNConsulting/frr to fortify IPv6 over IPv4 VTEP workflows and reduce risk in EVPNv6. Key changes include a DVNI IPv6 nexthop installation fix when using IPv4 VTEP, ensuring the correct encapsulation type is selected based on the actual underlay, and a set of Coverity-related improvements to EVPNv6 by addressing uninitialized variable warnings. These changes improve route reliability, prevent potential misrouting, and enhance overall stability of the overlay network, with measurable business value in reduced outages and smoother deployment of IPv6 capable dvni routes.

Jul 1, 2025Monthly summary for 2025-07: Stability and reliability improvements in LabNConsulting/frr addressing two high-impact bugs in bgpd and PBR. Key fixes include: 1) BGPD: Prevent crash on nexthop JSON query by resolving a race condition during peer deletion that could leave a dangling pointer in bgp_nexthop_cache.nht_info, preventing runtime crashes for commands like 'show ip bgp vrf all nexthop json' (commit dcd8cba5423ba5e6a878765b1a96eed2822efc9d). 2) PBR/Zebra: DSCP-only rule installation fix by correcting the Zebra family field, removing installation rejections and ensuring DSCP-based PBR rules install correctly (commit 9a6167852434a79cf60fb487d0aecf3c1218fecb).
