VLAN / Virtual Routing (VRF) ● Each VSAT Ethernet port acts as a virtual router (VRF)

● Enable multiple customers/services on a single VSAT

● End to end traffic separation (VLAN tagging or trunking)

● Full flexibility – separate routing per VRF (NAT, DHCP etc)

● Flexible QoS control – priority and weight per VRF

● Eliminates the need for an external VLAN switch

● Allows traffic separation between applications
