Vlan switching question

Hi

I have 2 CRS328-24P-4S+ + ccr1036

crs A the internet is conncted here

crs B another floow - there is a 2 port lacp connection between crs A & B

ccr1036 is connected to crs b

I have vlan 255 created on crs A - it has vlan defined up interfaces attached to my bridge (newbridge)

I have an eth port attached to newbridge and have pvid 255 so un tagged for it
i have the lacp attached to newbridge and 255 as tagged

on crs b

i have newbridge

i have the lacp attached with vlan 255 as tagged

i have a 2nd lacp to ccr1036 its attached to newbridge with vlan 255 as tagged

on ccr1036 i have interface vlan 255 off the bond interface

my question is if i don't have vlan 255 defined in crs B under the interface gui attached to the newbridge then packets for vlan7 don't make it from crs a to ccr (via crs b)

But if I create that interface on crs b it works - but I don't want to create an interface I want the vlan id to be used but i don't want the interface - so ipv6 automatically creates an address

do i just have to put with it ?

what i was thinking was to take my ISP modem - attach to crs A on vlan 255 -> trunk it to crs B and then trunk it to ccr, but in theory ... the internet has direct access to my crs A & crs B because of these interfaces

I'm hesitant to do that

the situation and question are not clear. clarify it for others to understand and suggest options

you mentioned vlan in interface in bridge?
you mentioned vlan 255 & 7?
and internet on 255 on A?
