Gateway Half Network Interface Configuration Screens
Neighbor Gateway Reachable Networks
configuring, NMMGR assumes no subnets.
Related screen:
• NETXPORT.NI.NIname.INTERNET
This path name corresponds to the Neighbor Gateways
screen. A Neighbor Gateway Reachable Networks screen
must be configured for each gateway configured in the
Neighbor Gateways screen.
IP mask
The IP mask masks 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 determine which gatewaythe network
transport will use by configuring an artificially high
hop count.
The transport always uses the gateway with the
smallest hop count. If the same hop count value is
configured for multiple gateways, then the network
transport will choose internally from among the routes
with equal hop counts.
Default value: None
Range: 1–32767
