CServer Source Route Type
When CServer Source is selected from the Route Type drop-down list, a subnet is defined and written
to the SubnetTable file. Subnets can only be defined for stream, cache, or stream/cache interfaces.
Interfaces are defined on the Interface Setup page (“Configuring the Interfaces,” page 4-109), and IP
addresses for the interfaces are set on the Server Setup page (“Configuring the Servers,” page 4-112).
Figure 4-49 shows an example of interfaces configured for multiple subnets on a Streamer.
Figure 4-49 Subnet Configuration Example on Streamer
Table 4-41 shows the possible configuration settings to use to define the subnets described in
Figure 4-49.
The Route Table entry for the subnet is defined by a network and subnet mask, and also includes a default
gateway. ARP is applied for any data packets that have a destination IP address within the defined subnet,
and the MAC address is returned. Any data packets outside the subnet are sent to the default gateway.
CServer Destination Route Type
When CServer Destination is selected from the Route Type drop-down list, an alternate gateway for a
destination subnet (based on the Network and Subnet Mask fields) is defined and written to the
RoutingTable file. The alternate gateway is used whenever the destination IP address of the data packet
falls within the destination subnet defined with the Route Type of CServer Destination.
Stream Control Route Type
When Stream Control is selected from the Route Type drop-down list, a subnet and default gateway is
defined for all stream control traffic, and the information is written to the Linux OS routing table file.
The Stream Control route type is available only when one of the interfaces is set to Stream Control in
the Interface Setup page. See the “Configuring the Interfaces” section on page 4-109 for more
information. The Linux OS routing table file is also used to store route information for the ingest and
management interfaces.
