Appendix B. IP Routing Support
B.1 Introduction
Offering state-of-the-art encapsulation based on the DVB Specification for Data Broadcasting (EN 301
192), the CMR-8500 provides the following configuration features:
• IP Encapsulation per Multi-Protocol Encapsulation (EN 301 192)
• Unicast Routing
• Multicast Routing
• Section Packing and Non-Section Packing
• 80,000 Configurable Routes
• 1 Default Route
• Multicast Zones
• IP Copy
• 802.1q VLAN
B.2 Route Configuration
Both Unicast and Multicast IP datagrams are encapsulated per the Multi-Protocol Encapsulation
specification. Routing of datagrams is accomplished by configuration of the ME Route Table, described
in the following section.
B.2.1 Unicast Routing
Unicast routing provides point-to-point delivery of IP datagrams. Routes for Unicast IP packets are
configured according to the following:
• IP Addresses, which fall into three classes, namely: A (0.0.0.0 to 127.255.255.255), B (128.0.0.0
to 191.255.255.255) and C (192.0.0.0 to 223.255.255.255).
• Medium Access Control (MAC) Addresses, which identify the destination device (next-hop) to
which the packets are sent. The least-significant bit of the first byte of the six-byte MAC address is
a ‘0’. For example, 0x00 11 22 33 44 55 is a Unicast address.
