COMMUNICATION PLAN

VRF3 has communication with VRF1

VRF3 has communication with VRF2

No communication between:

VRF1 and VRF2

VRF1 and VRF4

VRF2 and VRF4

VRF3 and VRF4

Intranet remote1 and Intranet remote2 have IP address plan overlapping (vlan 10 and vlan20 respectively). There is no inter-VRF communication from VRF3 to overlapping networks associated with vlan10 and vlan20.

Inter-VRF communication (VLAN to VLAN) are handled by static inter-VRF routes

VRF1 has access to the Internet via its Intranet remote 1 connection via vlan10

VRF2 has access to the Internet via its Intranet remote 2 connection via vlan20

VRF3 has no Internet access
