Description
BIRD filters used by the generated BIRD configuration have been updated to accept non-default routes announced by connected BGP peers.
Introduced new low prio PBR rule to ensure outbound VIP traffic is not misrouted, i.e. will not be leaked to primary network.
Blackhole logic is installed by default, but can be configured through frontend env variable DROP_IF_NO_PEER.
(The related blackhole routes are inserted by BIRD as well.)
Updated external-host test tool to either announce default routes (default behavior), or advertise certain pre-defined network routes.
Start external-host to announce non-default routes:
./docs/demo/scripts/kind/external-host.sh --default-route=no
