VLAN Scenario

In another scenario, to connect to the LAN, VRF-1, VRF-2, and VRF-3 use a single physical interface with

multiple tagged VLANs (instead of separate physical interfaces).

In this case, you configure three VLANs: VLAN-100, VLAN-200, and VLAN-300. Each VLAN is a member

of one VRF. A physical interface (gigabitethernet 0/1) attaches to the LAN and is configured as a tagged

interface in VLAN-100, VLAN-200, and VLAN-300. The rest of this example is similar to the non-VLAN

scenario.

This VLAN scenario often occurs in a service-provider network in which you configure VLAN tags for

traffic from multiple customers on customer-premises equipment (CPE), and separate VRF instances

associated with each VLAN are configured on the provider edge (PE) router in the point-of-presence

(POP).
