E.5 Using Bridge Point-to-Multipoint (BPM) Mode
See Appendix I. VIPERSAT NETWORK APPLICATION EXAMPLES for in-depth
information about using the BPM FAST Option.
Changing the Bridge Mode will leave QOS On. QOS should be turned Off prior
to setting the Bridge Mode.
Networks where modems traditionally act as routers – e.g., Vipersat-based satellite
communications systems – and include encryption devices are sometimes incompatible or require
difficult and unwieldy configurations. Additionally, the NP Interface limits the number of allowable
route tables. This, in turn, can limit the overall size of the network, particularly when OSPF (Open
Shortest Path First) dynamic routing protocol is used in the NP Interface.
In order to increase the flexibility and scalability of the satellite network with SLM-5650A modems,
the optional BPM Mode is a feature available with NP Interface operation whereby Layer 2 and
Layer 3 networks can operate simultaneously. When BPM Mode is selected, you can operate two
independent Layer2 networks and one Layer3 network simultaneously without interfering with each
other.
