C.2 Supported Network Configurations
When running in BPM Mode, the Advanced VSAT System supports Flat Networks, Flat Networks
with Routers, and VLAN Trunking network topologies.
C .2.1 F lat Network
In a Flat Network (Figure C-2), all devices are on the same IP subnet. This is a very easy-to-use
topology for simple and/or small networks.
Figure C-2. Flat Network
C .2.2 F lat Network with R outers
This variation of the Flat Network includes Routers at each site. With this topology (Figure C-3),
the Routers can be placed on the same subnet as if they were connected to the same Ethernet
Switch, and all core routing protocols such as OSPF, RIPv2, BGP, VRRP, etc. work as expected.
