How to configure a CCRXXXX as router
You dont have to configure a router as a router. It will router, like a switch will switch

VLAN trunk ports ?
Do you refer “Trunk” as a Link Aggreagtion? Thats called “Bonding” in Mikrotik (Linux).

You can combine this as well, a Bonding-Interface as a VLAN-Trunk.
