Vlan, 100% cpu, without CSR

Hi,
I have a problem with VLAN configuration on Mt, already tested different settings but not effectively.
He needs to do the sum of:
(RB1100) ether5 → trunk(3 vlan) → ether1 (rb951g)
in ether5 i have 3 vlans to ether be tagging or not …
ether1 vlan to the ether and VLAN to bridge or another port to bridge

Until now, the rapidly did:
vlan 10,20,30 to the port ether5 and the same to the port ether1
later, bridge and so on.
Problem one in 951 100% CPU
I read about the switch and the like. but without CSR can not do it.
HELP :slight_smile:
