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 will be sent to this gateway.
Interface (cpm0) indicates that the ONS 15600 Ethernet interface is used to reach the gateway.
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 (cpm0) indicates that the ONS 15600 Ethernet interface is used to reach the gateway.
Destination (172.20.214.92) is the destination host IP address.
Mask (255.255.255.255) is a 32-bit mask, meaning only the 172.20.214.92 address is a destination.
Gateway (127.0.0.1) is a loopback address. The host directs network traffic to itself using this
address.
Interface (lo0) indicates that the local loopback interface is used to reach the gateway.
Destination (172.20.214.93) is the destination host IP address.
Mask (255.255.255.255) is a 32-bit mask, meaning only the 172.20.214.93 address is a destination.
Gateway (0.0.0.0) means the destination host is directly attached to the node.
Interface (pdcc0) indicates that a SONET DCC interface is used to reach the destination host.
Destination (172.20.214.94) is the destination host IP address.
Mask (255.255.255.255) is a 32-bit mask, meaning only the 172.20.214.94 address is a destination.
Gateway (172.20.214.93) indicates that the destination host is accessed through a node with the IP
address 172.20.214.93.
Interface (pdcc0) indicates that a SONET DCC interface is used to reach the gateway.
