scripts/interop/lab.sh runs the daemon against FRR, BIRD and Routinator, each in a network namespace on one exchange LAN, and checks what every side ends up with: sessions and routes over IPv4 and IPv6 with their attributes, four-octet AS numbers, ADD-PATH, RFC 9234 roles and Only to Customer, RTR version 2 and invalid routes, route refresh, session resets, killed peers, a cut wire, the daemon stopped and killed, a table of a million routes and a restart under it, role mismatch and the prefix limit. All of it passes against FRR 10.5.1, BIRD 2.18 and Routinator 0.15.2. scripts/interop/real-rpki.sh checks the RTR client against a Routinator with the real RPKI: 713,258 IPv4 and 187,479 IPv6 VRPs and 3,379 ASPAs, the same numbers on both sides. What the lab found, fixed here: - A daemon restarted with its routes in the kernel removed them all at once, its table being empty until the peers had sent theirs again, and then put them back: no forwarding meanwhile. Routes of an earlier run are now kept for `stale_seconds` (120 by default) and only those nobody announced again are removed. A restart under a million routes takes 1.1 s to be in step, with nothing removed. - FRR ends a session it loses to a collision with a state machine error without a subcode, which was shown as "error code 5 subcode 0". CI gets a job that runs the lab. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
