H.2 OSPF v2 in a Shared Outbound Satellite Network
This section examines the challenges and solutions for using the SLM-5650A Satellite Modem
and Open Shortest Path First (OSPF) in a shared outbound/split path satellite network such as
Vipersat.
H.2.1 Shared Outbound Satellite Network Overview
A shared outbound network saves satellite bandwidth and reduces operating expenses by
allowing multiple remote terminals to share the same channel from a hub ground station.
Figure H-1 illustrates a satellite shared outbound network. Notably, the outbound interface at the
hub is not the same interface at which return traffic received. This is referred to as "split path."
