ISP - Routing IP Subnet to VLAN

HI Guys

Don’t know if I’m doing something wrong but here is the scenario.

We have a NNI from a Telco company, on the Mikrotik we have a /30 subnet.

Client A has a leased line installed from our provider and we have been provided the Vlan tag 101 that it will be supplied on the NNI. Please could someone give a straight forward way to route the /30 to this customer on vlan 101. On the other end the customer is using a draytek.

If someone could give me a hand that would be great!

Thanks

/ip address add address=A.A.A.A/30 interface=vlan101
