13.3 Routing Table
ONS 15454 routing information appears on the Maintenance > Routing Table tab. The routing table
provides the following information:
• Destination—Displays the IP address of the destination network or host.
• Mask—Displays the subnet mask used to reach the destination host or network.
• Gateway—Displays the IP address of the gateway used to reach the destination network or host.
• Usage—Shows the number of times the listed route has been used.
• Interface—Shows the ONS 15454 interface used to access the destination. Values are:
–
motfcc0—The ONS 15454 Ethernet interface, that is, the RJ-45 jack on the TCC2/TCC2P and
the LAN 1 pins on the backplane
–
pdcc0—A DCC/OSC/GCC interface
–
lo0—A loopback interface
Table 13-5 shows sample routing table entries for an ONS 15454.
Entry 1 shows the following:
• Destination (0.0.0.0) is the default route entry. All undefined destination network or host entries on
this routing table are mapped to the default route entry.
• Mask (0.0.0.0) is always 0 for the default route.
• Gateway (172.20.214.1) is the default gateway address. All outbound traffic that cannot be found in
this routing table or is not on the node’s local subnet is sent to this gateway.
• Interface (motfcc0) indicates that the ONS 15454 Ethernet interface is used to reach the gateway.
Entry 2 shows the following:
• Destination (172.20.214.0) is the destination network IP address.
• Mask (255.255.255.0) is a 24-bit mask, meaning all addresses within the 172.20.214.0 subnet can
be destinations.
• Gateway (172.20.214.92) is the gateway address. All outbound traffic belonging to this network is
sent to this gateway.
• Interface (motfcc0) indicates that the ONS 15454 Ethernet interface is used to reach the gateway.
Entry 3 shows the following:
• Destination (172.20.214.92) is the destination host IP address.
