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.
