4.2.4.5.2 Routing: Adding a Route
Figure 4-17. CMR-8500 Web Interface Add Route
The configurable parameters on the Add Route Page are:
• Enabled: Enable or Disable the route.
• Route Name: The name assigned to a given route.
• IP: The IP address assigned to a given route. A unicast route will fall within the range 0.0.0.0 to
223.255.255.255 (excluding broadcast or reserved IP addresses), and a multicast route will fall within
the range of 224.0.0.0 to 239.255.255.255.
• Mask: The subnet mask defines the range of IP addresses that will be supported by a particular route.
IP routes may NOT overlap.
IMPORTANT
The following demonstrates how the subnet mask defines the IP address range – the CMR-8500 uses
Classless Inter-Domain Routing (CIDR) notation for setting the subnet mask:
• 255.255.255.255 is 32 bits (used for an explicit route for a single IP address)
• 255.255.255.0 is 24 bits (used for a C-Class Mask)
• 255.255.0.0 is 16 bits (used for a B-Class Mask)
• 255.0.0.0 is 8 bits (used for an A-Class Mask)
