RB450Gx4 vlans questions

RouterOS Beginner Basics

Hello,
Again I’m a bit lost related to what would be the best approach in my case

  1. router RB450Gx4
  • ether1 WAN
  • ether5 trunk port =>SW1
/interface bridge vlan
add bridge=BR1 tagged=BR1,ether5 vlan-ids=80
add bridge=BR1 tagged=BR1,ether5 vlan-ids=99
add bridge=BR1 tagged=ether5,BR1 vlan-ids=10
add bridge=BR1 tagged=ether5,BR1 vlan-ids=100

Interface vlan

/interface vlan
add comment="subnet[mgmt vlan] 192.168.99.0/24" interface=BR1 name=BASE_VLAN vlan-id=99
add comment=":: subnet 192.168.50.0/21" interface=BR1 name=vlan10 vlan-id=10
add comment="subnet 192.168.100.0/21" interface=BR1 name=vlan100 vlan-id=100
add comment="subnet[wireless] 192.168.80.0/24" interface=BR1 name=vlan_80 vlan-id=80

So far so good,

However I’m interested if makes any difference to use switch chip in this case… and if so… how to port mentioned config to switch config ?

With your description of use case and config shown, performance difference between the two setups would be negligible.

If, OTOH, you’d have another trunk on, say ether4, and there would be some traffic between ether4 and ether5 inside same VLAN, then there would be difference (in CPU load if nothing else).

I have that router and use bridge vlan filtering with no issues. keep it simple you will be happy.

Thanks,

Indeed once is it working don’t change it,
Was more curios about taking the 2nd approach, to use the switch mode :slight_smile:

  • don’t know if normal,
    I do have sync internet 1G up 1G down,
    …and I see if I put something to download and speed is over 500mbs , CPU load reaches ~38% …

Sounds about right.
