Mikrotik With Cisco VLAN

Please find a solution for this,

I have an CCR with 10 Hotspots which was announced on 10 interfaces,
Now i am planning to make this all Hotspots to be announced on one Interface of the CCR with VLAN,
But, coming to my Lan, its a open LAN, wherein all the 1500 users are in one LAN

So, kindly assist me how to configure this CCR with Cisco 2950-T which has two Gig Ports.
