I'm wondering about the new bridge implementation since 6.40.x. Is it recommended to have a single or multiple bridges when a bunch of tagged vlans should be bridged to different ether ports? For example, let's assume we have three physical ether ports (and no switch-chip) and three tagged vlans;
Vlans:
Code: Select all
/interface vlan
add interface=ether1 name=ether1-vlan100 vlan-id=100
add interface=ether1 name=ether1-vlan200 vlan-id=200
add interface=ether2 name=ether2-vlan200 vlan-id=200
add interface=ether2 name=ether2-vlan300 vlan-id=300
add interface=ether3 name=ether3-vlan100 vlan-id=100
add interface=ether3 name=ether3-vlan300 vlan-id=300
1) Dedicated bridge for each vlan:
Code: Select all
/interface bridge
add name=bridge-vlan100
add name=bridge-vlan200
add name=bridge-vlan300
/interface bridge port
add bridge=bridge-vlan100 hw=no interface=ether1-vlan100
add bridge=bridge-vlan100 hw=no interface=ether3-vlan100
add bridge=bridge-vlan200 hw=no interface=ether1-vlan200
add bridge=bridge-vlan200 hw=no interface=ether2-vlan200
add bridge=bridge-vlan300 hw=no interface=ether2-vlan300
add bridge=bridge-vlan300 hw=no interface=ether3-vlan300
2) Single bridge with all vlans assigned to the same bridge and bridge vlans:
Code: Select all
/interface bridge
add name=vlan-bridge
/interface bridge port
add bridge=vlan-bridge hw=no interface=ether1-vlan100
add bridge=vlan-bridge hw=no interface=ether3-vlan100
add bridge=vlan-bridge hw=no interface=ether1-vlan200
add bridge=vlan-bridge hw=no interface=ether2-vlan200
add bridge=vlan-bridge hw=no interface=ether2-vlan300
add bridge=vlan-bridge hw=no interface=ether3-vlan300
/interface bridge vlan
add bridge=vlan-bridge tagged=ether1 vlan-ids=100,200
add bridge=vlan-bridge tagged=ether2 vlan-ids=200,300
add bridge=vlan-bridge tagged=ether3 vlan-ids=100,200
Is there any benefit (besides better manageability)?
Is there any performance difference (on an CCR for Example)?
Thanks
