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 is limited to connected interface routes only.

Inter-VRF communications (VLAN to VLAN) are handled by dynamic inter-VRF routing.

VRF1 and VRF2 can both access the Internet via shared VRF3 vlan100, however additional HW ACLs are now required to prevent data from VRF1 being routed via Internet access router back to VRF2 and vice-versa.
