RB450g Switch rules 2 trunks

I need to trunk 3 ports on an RB450g (ether2 and ether3 belong to a bond with WDS RocketM5’s in the middle) and ether1 is trunk port to a cisco switch.

On my switch I have the following:

int fa0/24
switchport mode trunk
switchport trunk vlan 60,70

I have read the wiki set but the example given is for 1 trunk port and 3 access ports. If someone would be so kind to help me shed some light on this I would be grateful.

Do you mean multiple VLAN on access port? If so, how do you determine what VLAN-ID is set for a specific packet?

No I do not. I need 3 ports on the RB450g to be trunk ports. Ether2 and Ether3 are part of a bonding with Rocket M5’s in WDS mode. I need to carry 2 vlans from one site to the other. I need the ports to be trunked.
