So if I create a VLAN 10 subinterface for both eth1 and eth2, what happens? The device accepted the configuration. Does it actually work just like a big L2 domain sharing the same L3 VLAN interface? Basically like a Cisco L3 switch, logically separating the L2 domain from the L3 SVI?
If not what does the command do? How does eth1.10 and eth2.10 communicate with each other and outside?
