We have two VLAN's
VLAN 1-192.168.18.0/24 (with secondary addressing)
In order to migrate services to new hardware in VLAN 2, we need to divert traffic or at least determine what devices within VLAN 1 are still trying to talk to legacy VLAN 1 device?
Host routes won't work (directly connected interfaces), nor NAT (no interface to apply it to).
Is the only way to determine this via a VACL in VLAN1 with logging keywords?
