hi guys
just want to know

i have a trunk with vlan100(green) and vlan200(yellow) coming into my rb750 ether 1

while my default network is on the default setting which i assume is vlan1

i have another trunk out of ether 5 that should trunk out vlan1(black) and vlan200(yellow)

while my vlan100(green) is bridge to a ether2

how do i trunk my ether1 vlan200(yellow) so that it goes out ether 5 unmodified ?

what i have done is..
for vlan100 green, i created a vlan100 and attached it to ether 1 and bridge it to ether2 so it comes out untag

but for vlan200 how do i, do the configuration ?

nvm i found a way that works.. but not sure if its the most efficient way…

create vlan200(yellow) on ether1 and 5
create a bridge and bridge them both, the vlan not the ether interface

while vlan1(black) create a bridge and bridge it to a ether2/masterport
