Multiple IP addresses and switch

Hello!
I have a wire coming from ISP with static public IP address block (5.5.5.96/28) into CCR-1016 ether1.
I want to use ether2 interface for LAN (192.168.1.0/24) and I want to use ports ether3/ether4/ether5 etc. for servers who are directly connected into these ports.
And I want these servers to use public IPs that ISP gave me (e.g. 5.5.5.99, 5.5.5.100, 5.5.5.101).
My first guess would be to set ether1 as master-port for ether3,4,5 and use these ports as switch, then all I had to do would be configure those public IPs in servers and done.
But it seems like there is no switching ability in CCR series. Do I have to buy a switch to put it in between ISP and CCR router or is there any other way to achieve my goal?
Thanks!

Create a bridge and place the interfaces on the bridge.
