I'm new to MikroTik, but have done a lot of reading of the wiki and examples. But I'm still a bit confused on the configuration that I need. I put together a network diagram, that I hope is helpful in explaining what I need for the CRS317:

What I want is Ether1-4 to be trunk ports, accepting ANY VLAN from my server. Eth16 is also a trunk port, going to the border router. I will also be connecting a network cable to the management port and want it to have a management IP of 10.13.2.12. I just need L2 functionality in the CRS317. The CCR2004 will do all the routing.

I've hacked together a config, which I'm sure is wrong and needs serious modifications. Any help would be greatly appreciated!

/interface bridge
add name=bridge1 vlan-filtering=no
/ip address
add address=10.13.2.12/24 interface=bridge1
/interface bridge port
add bridge=bridge1 interface=ether1 hw=yes
add bridge=bridge1 interface=ether2 hw=yes
add bridge=bridge1 interface=ether3 hw=yes
add bridge=bridge1 interface=ether4 hw=yes
add bridge=bridge1 interface=ether16 hw=yes
/interface bridge set bridge1 vlan-filtering=yes

Thanks!

After more research I've modified the proposed configuration. Any input is welcome on changes needed. I also need the MTU set to 9000 on all ports, as I'll be using VMware NSX-T.


/interface bridge
add name=bridge1 vlan-filtering=no
/ip address
add address=10.13.2.12/24 interface=MGMT
/ip route add distance=1 gateway=10.13.2.1
/ip dns
set servers=10.13.2.200,10.13.2.201
/interface bridge port
add bridge=bridge1 interface=ether1 hw=yes
add bridge=bridge1 interface=ether2 hw=yes
add bridge=bridge1 interface=ether3 hw=yes
add bridge=bridge1 interface=ether4 hw=yes
add bridge=bridge1 interface=ether16 hw=yes
/interface bridge vlan
add bridge=bridge1 tagged=ether1,ether2,ether3,ether4,ether16 vlan-ids=1-4094
/interface ethernet
set [ find ] l2mtu=10218 mtu=9000
/interface bridge set bridge1 vlan-filtering=yes
/system identity

/system ntp client

Thanks! I've significantly modified my configuration based on your links and more research. Can you review to see if I made any mistakes?

Which method have you chosen? if its bridge vlan filtering I can be of some assistance but I need to see the entire config not excerpts.

One thing: switch (and you're using CRS317 as a switch) doesn't need VLAN interfaces for all VLANs that are passed between switched ports. Meaning you only need interface for management LAN (in your case that's ether1 used as MGMT interface), but you don't need any of vlan 26xx-* interfaces. For OOB management I wouldn't bridge ether1 together with "service" ports.

And since you don't need VLAN interfaces on bridge, bridge interface itself doesn't have to be member of any of VLANs (which is already true according to the above config excerpt).

Do you actually have devices (CCR2004 and CRS317) at hand? If yes, try to configure them (as a lab), see what doesn't work and ask about particular things. And post (non-working) config so we can point out concrete errors. If you don't have the equipment with you yet, then I don't see any point in constructing configuration files because you don't have feedback from device and it's harder for you to learn ROS concepts. We can go on and on with quasi-theoretical discussions but I have a feeling that we wouldn't have to discuss certain things if you could try them hands-on.
