UDP Multicast (Point to Multipoint) Server Setup Example

When the Terminal Server is configured to operate in either the Point-to-Multipoint or Multipoint-to-
Multipoint UDP mode, a static route must be created to direct how the unit handles the transmission of
the multicast UDP packets. This static route must define the "Outgoing Interface" for the Orbit to use to
get to a Destination Prefix of the full multicast subnet of "224.0.0.0/4".
It is also recommended that a multicast static route be configured on each multipoint unit.
NOTE
If a unit participates in multiple multicast groups, and each of these groups are accessible via
different interfaces, then a separate static route must be created for each group and interface
combination (i.e. 224.0.0.3/32 via ETH1 and 224.0.0.4/32 via ETH2), instead of the full
multicast subnet.
Summary of Configuration Steps (be sure to follow these steps in order):
1. Configure an IPv4 Static-Route for the Multicast Subnet.(Static Neighbor Entries)

Configure Destination Prefix (dest-prefix)

Configure Outgoing Interface (outgoing-interface)
2. Configure Orbit Serial Terminal Server

Configure which Serial Port to use as Terminal Server

Configure UDP as Protocol

Configure UDP Mode to use Point-to-Multipoint
