What do you need to set up in the network to allow traffic to be routed from one VLAN to the other?

Inter-VLAN routing is what makes traffic move between different VLANs. Each VLAN is its own broadcast domain, so devices in one VLAN can’t reach devices in another without a router (or a Layer 3 switch) that can route between those networks. To implement it, set up a Layer 3 device with an interface for each VLAN (SVIs on a switch or subinterfaces on a router), assign IP addresses in the respective subnets, and have hosts use the device’s VLAN-specific IP as their default gateway. That device will then route packets between the VLANs. While a default gateway on hosts and routing mechanisms like static routes or routing protocols exist, they don’t by themselves enable cross-VLAN routing—the actual ability to route between VLANs comes from inter-VLAN routing.
