Point-to-Point (Router) Network Interface Configuration Screens
Neighbor Gateway Reachable Networks
Addresses are made up of a network portion and a
node portion. The possible classes of network
addresses have the following forms:
Class C: C nnn.nnn.nnn xxx
Class B: B nnn.nnn xxx.xxx
Class A: A nnn xxx.xxx.xxx
where nnn is a value ranging from 000 to 255,
representing eight bits of the network portion of an
address and xxx is a value ranging from 000 to 255,
representing node portion of the address. Note the
network and node portions of all zeros or all ones are
not allowed. These are special values.
The leftmost group of nnn has the following ranges for
each address class:
Class C: 192–223
Class B: 128–191
Class A: 001–126
Default value: None

The network address (network portion of the IP
address) configured in this screen must match the
neighbor gateway IP internet address configured in
the current screen.
Configured reachable networks IP network address
Enter the internet addresses of the remote networks
that can be reached through the gateway whose
network address is configured in the previous field.
You can also designate this gateway as a default
gateway by entering an “at” sign (@) in one of the
Configured reachable networks IP network
address fields. The network will route messages to the
default gateway if it is unable to locate their
destination by any other means. The default gateway
will then attempt to locate the destination.
When specifying reachable networks, entering only the
network portions, and optionally the subnet, of the IP
address (setting the node portion to all zeros) allows
this node to communicate with any other node on the
remote network.
