18.1 Generic Routing Encapsulation (GRE) and IP Tunnelling The STM SatLink VSAT supports configuration of one IP tunnel from its DVB (Satellite) interface with Generic Routing Encapsulation (GRE) as specified in RFC 2784. Only the tunnel destination IP address and the subnet to be tunnelled need to be specified when setting up a GRE tunnel over the SatLink network since the GRE tunnel by default will apply the reachable DVB interface IP address as the tunnel source IP address.
Page 86
Example # ip addroute 225.0.0.2 255.255.255.255 4 The above configuration will forward multicast datagrams with IP address 225.0.0.2 from the STM SatLink VSAT LAN interface to the GRE tunnel identified by the specific GRE interface ID.. Forwarding of multicast IP traffic from DVB interface to GRE interface is not supported...
Page 87
When operating in re-direct mode, the IP address of the TCP PEP Server in the Hub must be configured in the STM SatLink VSAT. If the VSAT is authorised to use PEP, this is normally performed remotely by the SatLink Hub when the VSAT logs on to the network. Alternatively, the VSAT user can locally...
Page 88
When the STM SatLink VSAT is licensed to support HTTP acceleration, the function can be enabled and disabled. By default the HTTP accelerator is disabled. HTTP acceleration operates in the context of TCP acceleration.
The Critical Data PHB and Real Time Video Conferencing PHB group are available as standard only on the STM SatLink 1910 and requires the QoS4 SW license key to be configured on the STM SatLink 2000, 1000, 1900, and 1901 models. The table below shows which QoS Groups on which VSAT models that require the QoS4 SW license key to be configured.
IEEE Std 802.1Q defines an Ethernet frame format that can be used to separate virtual VLANs over a shared physical Ethernet link. When the STM SatLink VSAT is licensed to support virtual LAN (VLAN) trunking, it is capable of keeping the traffic for different VLANs separated over the satellite link, too. The VSAT can then carry the traffic for multiple VLANs and allows you to extend the VLANs across the SatLink network.
Page 93
It is assumed that the tunnel destination of each GRE tunnel terminates in a device that is configured to map to the same VLAN as the local end, as required. Note that the STM SatLink network is an IP network and not an Ethernet MAC bridge, and thus the VLAN tag will not be carried through the SatLink network, but must be regenerated locally at the GRE egress point, if required.
Ethernet interfaces connected to the STM SatLink VSAT operate in VLAN trunk mode (802.1Q) and provides correct user priority tag values. Note that the STM SatLink network is an IP network and not an Ethernet MAC bridge and thus the user priority value will not be regenerated at the egress of the SatLink network.
SatLink VSAT User Guide 19. Extensions for Mobile VSAT The extensions in this appendix are available for the SatLink 1910 VSATs with the MOBILE software license key set. For the transmit inhibit function described in section 19.1, additionally the SatLink 100 plug-in card, revision 2.0 or newer is required to be installed.
Page 97
19.2 GPS Interface The SatLink 1910 with the MOBILE license key set can automatically read its GPS position from an external GPS via the NMEA-0183 protocol and hence constantly have available correct GPS position for use to calculate correct delay to the satellite to anble the logon burst to be sent with correct timing when the mobile VSAT wants to enter a SatLink network.

VSAT has been correctly installed and commissioned by the Network Operator, it is convenient to enable rx autostart and tx autostart as described in section 9.5. When rx autostart and tx autostart are set to off (disabled), the STM SatLink VSAT will make one attempt to acquire the forward link when issuing the CLI command .
A rough outline of the procedure is as follows: The STM SatLink VSAT tunes to the transport stream of the forward link that it has pre-configured as ”start-up” forward link. There it reads the NIT. The NIT PID value is hard-coded in the SatLink VSAT.
SatLink VSAT User Guide The STM SatLink VSAT can report the following Receiver State status: Tuning transponder one Tuning transponder two Tuning transponder three Waiting for NIT (transponder one) Waiting for PAT (transponder two) Waiting for PMT (transponder two) Waiting for RMT (transponder two)
