[PATCH pve-network 13/16] tests: test route filtering mechanism with multiple zones/controllers

Stefan Hanreich
2026-04-14T16:34:46Z

When utilizing multiple controllers and assigning them to EVPN zones
selectively, the outgoing routes get filtered - so EVPN controllers
only announce routes of zones/vnets they are explicitly assigned to.
This test case creates two zones and assigns one controller to both,
another controller to only one zone to test the outgoing route
filtering mechanism.
