The VRF-aware device has six separate VRFs configured, they are named: red, green, blue, orange, shared and overlap. The VRF-aware device has static routes to two router networks (orange router and shared router). It also peers to two OSPF routers (OSPF red peer and OSPF orange peer), one i-BGP peer (i-BGP green peer) and one RIPv2 peer (RIP blue peer), and one e-BGP peer (e-BGP shared Internet peer) that allows Internet access. None of the peer devices are VRF aware. Dynamic inter-VRF communication allows selected VRFs to access a common shared Internet connection.

Each VLAN(s) is associated with a VRF instance.

Each VRF instance also has its own unique IP local interface and associated local IP address.

Each VRF contains its own separate IP routing domain and separate (OSPF) routing protocol instance or (BGP/RIP) address-family.

The VRF instances red, green, blue, and orange, are all able to access the Internet via VRF shared. They also have filtered access to ‘shared router’ subnets. All inter-VRF communication between VRFs red, green, blue, and orange is blocked.

BGP, route-maps, and Access Control Lists (ACLs) are used to ‘leak’ selected routes between VRFs to allow filtered inter-VRF (IVR) communication.
