[PATCH pve-network 11/16] test: evpn: add legacy test

Stefan Hanreich
2026-04-14T16:35:24Z

This is the exact same as the ebgp test - but explicitly sets the
bgp-mode to legacy. The intention of this test is to check if setting
the legacy mode explicitly results in the exact same settings as the
ebgp test, which does not set any bgp-mode so the FRR config
generation automatically falls back to legacy mode.
