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.
