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
