Answer:
Create a trunk link on the switch port to the router interface and configure a subinterface on that router interface.
Explanation:
VLANs are platforms configured on a switch xto give more control on how frames are broadcast. The default Vlan is the Vlan 1 which holds all the switch ports in the switch. It is used to segment a switch to different broadcast domain.
A trunk port is used to carry multiple Vlan frames or tagged Vlan. It is also configured on switch ports to a router for inter-Vlan routing, where Vlan tags are routed between VLANs in a network.
On the switch port, used the " switchport mode trunk" and switchport trunk Vlan 200 command on the interface leading to the router interface. And use the "'interface' ' interface id' . 'vlan id'" command on that router interface.
