CDD-880 Multi Receiver Router

Figure F-3. CDD-880 HTTP Interface – Configuration | Network | Routing Page
For each individual mesh connection, the VMS enters a SHOD (Single Hop On Demand) at
the Hub site CDD-880 demodulator as shown in Figure F-3. The Filter Table lists the
Destination Network IP/Mask and a Filter Map. This Filter Map corresponds to the Hub site
CDD-880 demodulator that is tuned to the remote site originating the mesh.
The intent of this filter rule is to block any packets originating from R1 that are destined to
R2. This prevents traffic to the meshed remote site from going on to the Hub LAN and being
retransmitted by the TDM (CTOG-250) outbound.
5. Single Hop On Demand (SHOD): The VMS adds an additional SHOD filter to the Hub
CDD-880 for this subnet. If the traffic subnet is part of a subnet that can be described in one
route statement (e.g., a subset of the same Class C that is the management subnet), this is
