VLAN - Virtual Routing (VRF) solution

Each VSAT Eth port acts as a virtual router (VRF)

Allows serving multiple customers on a single VSAT

End to end traffic separation (VLAN tagging or trunking)

Eliminates the need for an external VLAN switch

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


Flexible QoS control – priority and weight per VRF

Allows traffic separation between applications

Secure and separate critical applications
