correct i already did this before opening the question here:
I have
user@qfx> show configuration vlans test
vlan-id 4;
l3-interface irb.4;
and
user@qfx> show vlans test
Routing instance VLAN name Tag Interfaces
default-switch test 4
ae0.0*
user@qfx> show configuration interfaces ae0 | display set
(....)
set interfaces ae0 unit 0 family ethernet-switching vlan members 3-4
(....)
but i was wondering about one step: having more interfaces where this vlans need to be allowed only for layer 2 than in the above output i can not differentiate in whcih interfaces is Layer 2 o3 but i think what i am writing here does not make sense.
I shoud threat this topic as SVI in cisco world i would say, right?
