Neighbor Gateway Reachable Networks
To allow this node to communicate with other subnets
on the local network, enter the decimal equivalent of
the subnet in the IP network address field and enter
the subnet mask in the IP mask field. If you do not
enter a subnet mask, one of the following occurs:
If the IP address is the same as the node you are
configuring, the IP mask configured in the IP
Protocol Configuration screen (Figure 8-5) is used.
If the IP address is different from the node you are
configuring, NMMGR assumes no subnets.

.INTERNET
This path name corresponds to the Neighbor
Gateways screen. ANeighbor GatewayReachable
Networks screen must be configured for each
gateway configured in the Neighbor Gateways
screen.
IP mask The IP mask identifies a portion of the IP address for
subnets. The subnet is specified in the same format as
an IP address, that is, the 32-bit mask is grouped in
octets expressed as decimal integers and delimited by a
“. or a space. For example, a mask for a class A address
with the subnet field being the first 8 bits of the node
portion would be expressed as 255 255.000.000. The
default is no IP mask.
Configured
reachable
networks hops
Enter the internet hop count to the reachable network
whose IP address is configured to the left of the hops
field. (The internet hop count is the number of full
internet gateways that will be used to route a message
to the destination network. If two partner gateway
halves are used as part of the internet route, they are
counted as one hop.)
Hop count is used internally to determine which
neighbor gateway (if more than one exists) is on the
shortest path to the remote network. If more than one
gateway can reach a given remote network, and the
number of hops to the remote network is equal for each
gateway, you can specify which gateway the network
transport will use by configuring an artificially high
hop count. The network transport will always use the
gateway with the lowest hop count. If the same hop
