HP e3000/iX Network Planning and Configuration Guide (36922-90037)

Chapter 6 117
Configuring a LAN, Token Ring, FDDI, 100VG-AnyLAN, 100Base-T Node
To Configure Neighbor Gateways
Step 5. Repeat steps 2, 3, and 4 for each remote reachable network. The
information configured in this screen can extend to more than
one page, 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 selected configuration screen (LAN, Token Ring, FDDI,
100VG-AnyLAN, or 100Base-T). Proceed to Chapter 10, “Validating
Network Transport and Cross-Validating with SYSGEN,”
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 selected
configuration screen (LAN, Token Ring, FDDI,
100VG-AnyLAN, or 100Base-T).
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. Only one gateway can be
designated as a default gateway for each HP 3000
Series 900 system.
IP Mask
(Optional) The fields under this heading allow you to specify a
subnet mask for each reachable network. This mask is
optional.
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.
