Network Planning

Planning Prerequisites
In addition to the topics about planning your network, you should consider
the following:
D
Do you need to cluster your nodes?
How many nodes are interconnected in your network? A network of
up to 254 nodes can be designed. For networks consisting of more
than 12 nodes, you will need to group nodes together in clusters. For
networks with 12 or less nodes, clustering is optional. More
information on clusters is explained on the next paragraph titled
Clusters.
D
Note the LAN module's hardware address.
The LAN module's hardware address is written on a label on the back
panel of the LAN module. You may record this in the worksheets
appendix, page A1. For the NetRunner 75E, the hardware address is
written on a label on the back panel of the LAN/WAN module.
D
Traditional IP routing considerations
(Refer to the Integration Router manual, which contains more
information on these prerequisites):
- Network addressing and subnetting. Acquire the necessary IP
addresses from the Internet Authority.
- Node addressing. You must assign unique IP addresses to all the
nodes on your network.
- Default gateways. There must be a default gateway (router)
established.
- Domain Name Servers (DNS). Host tables that must be updated
to reflect the new network architecture established by routing.
- Bootp. Any machine that requires Bootp during startup must
either be on the same LAN segment as the Bootp host, or the
Bootp host must be able to download Bootp through the
Integration Router.
D
Traditional IPX routing considerations
(Refer to the Integration Router manual which contains more
information on these prerequisites):
- Unique network numbers for each LAN segment. (In bridged IPX
networks, all LAN segments have the same network number.)
- All servers on a network segment must have unique network
numbers, and these numbers must not be the same as any LAN
segment network number.
- The WAN for all nodes in one cluster is considered as one virtual
LAN segment. Thus, only one network number is required for the
WAN.
