Inter vlan routing using old Legacy Method

Inter-vlan Routing Using Legacy Method :
• Historically, the first solution for inter-VLAN routing relied on routers with multiple physical interfaces.
• Each interface had to be connected to a separate network and configured with a distinct subnet.
• In this legacy approach, inter-VLAN routing is performed by connecting different physical router interfaces to different physical switch ports.
• The switch ports connected to the router are placed in access mode and each physical interface is assigned to a different VLAN.
• Each router interface can then accept traffic from the VLAN associated with the switch interface that it is connected to, and traffic can be routed to the other VLANs connected to the other interfaces.

nicely explained sir, but i have a doubt. to my knowledge vlan information is not sent over access port, don't we need to create a trunk first?
