Configuring a X.25 Node
Configure Neighbor Gateways
if necessary, to allow configuration of up to 2550 reachable networks per
link (255 pages and 10 reachable nets per page). If you need to
configure more than 10 networks, press the
[Save Data] key then press
the
[Next Page] key to enter more networks.
Step 6. After you have finished entering the IP addresses of all the reachable
networks, press the
[Save Data] key. Press the [Prior Screen] key to
return to the Neighbor Gateways screen.
Step 7. Back at the Neighbor Gateways screen, after you have finished adding
all of the neighboring gateways, press the
[Prior Screen] key to return to
the X.25 Configuration screen. Follow the instructions for step 7 in the
section in this chapter titled “To Configure an X.25 Network.”
Fields If you have identified any neighbor gateways, then you will also be
identifying: 1) the IP Network Addresses of all of the networks that you
can reach through that gateway, and 2) the number of hops
(corresponding to the number of gateways) that a packet passes
through to reach a remote network from the local network. Two
gateway halves count as one hop.
Neighbor Gateway IP Internet Address
The IP address of the gateway whose name you have
specified on the Neighbor Gateways Screen. The IP
address is in the same format as the LAN
Configuration screen.
IP Network Address
In the fields under this heading, you list the IP
addresses of all of the networks that you will be able to
reach through the gateway you are configuring. You
also use this field to indicate whether or not the
gateway is to serve as a default gateway by entering an
at sign (@) to specify that it is a default gateway.
Multiple gateways can be designated for each HP e3000
systems.
IP Mask (Optional)
The fields under this heading allow you to specify a
subnet mask for each reachable network. This mask is
optional. For details on deriving an IP subnet mask, see
Chapter 2 , “Networking Concepts.”
Hops
In the fields under this heading, enter the number of
hops corresponding to the number of gateways that a
packet travels to reach a remote network from a local
network.
