CRS326 - bridge VLAN problam

I'm having problems with new bridge VLANs implementation on RouterOS 6.41.X.
CRS-1 and CRS-2 are two CRS326-24G-2S+, configured as follow:

CRS-1:
Code: Select all
/interface bridge
add fast-forward=no name=bridge
/interface vlan
add interface=bridge name=vlan-100 vlan-id=100
/interface bridge port
add bridge=bridge interface=ether1
add bridge=bridge interface=ether2
add bridge=bridge interface=ether3
add bridge=bridge interface=ether4
add bridge=bridge interface=ether5
add bridge=bridge interface=ether6
add bridge=bridge interface=ether7
add bridge=bridge interface=ether8
add bridge=bridge interface=ether9
add bridge=bridge interface=ether10
add bridge=bridge interface=ether11
add bridge=bridge interface=ether12
add bridge=bridge interface=ether13
add bridge=bridge interface=ether14
add bridge=bridge interface=ether15
add bridge=bridge interface=ether16
add bridge=bridge interface=ether17
add bridge=bridge interface=ether18
add bridge=bridge interface=ether19
add bridge=bridge interface=ether20
add bridge=bridge interface=ether21
add bridge=bridge interface=ether22
add bridge=bridge interface=ether23
add bridge=bridge interface=ether24
add bridge=bridge interface=sfp-sfpplus1
add bridge=bridge interface=sfp-sfpplus2
/interface bridge vlan
add bridge=bridge tagged=ether24 vlan-ids=100
/ip address
add address=192.168.100.1/24 interface=vlan-100 network=192.168.100.0
/ip dhcp-client
add dhcp-options=hostname,clientid disabled=no interface=bridge
/system identity
set name=CRS-1
/system routerboard settings
set boot-os=router-os
CRS-2:
Code: Select all
/interface bridge
add fast-forward=no name=bridge
/interface vlan
add interface=bridge name=vlan-100 vlan-id=100
/interface bridge port
add bridge=bridge interface=ether1
add bridge=bridge interface=ether2
add bridge=bridge interface=ether3
add bridge=bridge interface=ether4
add bridge=bridge interface=ether5
add bridge=bridge interface=ether6
add bridge=bridge interface=ether7
add bridge=bridge interface=ether8
add bridge=bridge interface=ether9
add bridge=bridge interface=ether10
add bridge=bridge interface=ether11
add bridge=bridge interface=ether12
add bridge=bridge interface=ether13
add bridge=bridge interface=ether14
add bridge=bridge interface=ether15
add bridge=bridge interface=ether16
add bridge=bridge interface=ether17
add bridge=bridge interface=ether18
add bridge=bridge interface=ether19
add bridge=bridge interface=ether20
add bridge=bridge interface=ether21
add bridge=bridge interface=ether22
add bridge=bridge interface=ether23
add bridge=bridge interface=ether24
add bridge=bridge interface=sfp-sfpplus1
add bridge=bridge interface=sfp-sfpplus2
/interface bridge vlan
add bridge=bridge tagged=ether1 vlan-ids=100
/ip address
add address=192.168.100.2/24 interface=vlan-100 network=192.168.100.0
/ip dhcp-client
add dhcp-options=hostname,clientid disabled=no interface=bridge
/system identity
set name=CRS-2
/system routerboard settings
set boot-os=router-os
Connections are as follow:

LAN ---> (ether1) CRS-1 (ether24) <---> (ether1) CRS-2

CRS-1 and CRS-2 can ping each other over VLAN 100 (192.168.100.0/24), BUT when I enable "vlan-filtering" (/interface bridge vlan-filtering=yes) they stop to respond...
What am I doing wrong?

You are missing the management port.

You need to add the bridge interface itself as a tagged port in /interface bridge vlan.

I added VLAN 1 as management and bridge as tagged port, configured as follow, but problem still remain...

CRS-1:
Code: Select all
/interface bridge
add fast-forward=no name=bridge vlan-filtering=yes
/interface vlan
add interface=bridge name=vlan-100 vlan-id=100

add bridge=bridge interface=ether1
add bridge=bridge interface=ether2
add bridge=bridge interface=ether3
add bridge=bridge interface=ether4
add bridge=bridge interface=ether5
add bridge=bridge interface=ether6
add bridge=bridge interface=ether7
add bridge=bridge interface=ether8
add bridge=bridge interface=ether9
add bridge=bridge interface=ether10
add bridge=bridge interface=ether11
add bridge=bridge interface=ether12
add bridge=bridge interface=ether13
add bridge=bridge interface=ether14
add bridge=bridge interface=ether15

Ok, now all seems to be good... I only had to wait some time, maybe to permit a flush of SVL/IVL
Than you!
