Hello,
As I understand, you are installing a virtual machine on the Server-PT (ESXi) to play the role as router (Mikrotik).
Create Virtual Switch with Uplinks connected to SW-Core (2950T-24), this Uplinks should be configured on switch as Trunk port.
And from virtual machine side as each router, you need for minimum two legs connected to two separated tagged port groups each one with a specific VLAN. (VLAN for 10.0.1.x and one for 10.0.2.x)
Please consider marking this answer "correct" or "helpful" if you think your question have been answered correctly.
Cheers,
