IPX Routes
Your system maintains a table of routes to other IPX networks. You can:
■
Use RIP mode to exchange routing information dynamically.
■
Use the Administration Console to make static entries in the table.
Important
Considerations
Consider the following guidelines when you set up an IPX route:
■
The first line in the output (the status line) indicates whether:
■
IPX forwarding is enabled.
■
IPX RIP mode is active.
■
IPX RIP mode triggered updates are enabled.
■
IPX SAP mode is active.
■
IPX SAP triggered updates are enabled.
■
The secondary route/server option is enabled on the system.
■
The route table display shows the range for routing table Primary
entries in the n-m format, where n is the current number of entries
and
m
is the maximum number of Primary entries.
■
If your system has extended memory, the route table display includes a
range for the routing table
Secondary
entries in the
N-M
format,
where N is the minimum number of entries and M is the maximum
number of secondary entries. If no range is displayed, the system does
not have extended memory, so the number of route table entries is a
fixed number.
■
A Secondary route entry can replace a Primary route entry when the
Primary route is removed from the routing table for any reason (for
example, if the route reaches its age limit).
■
To view entries for any Secondary routes:
■
Establish alternate paths to the same IPX network.
■
Enable the IPX Secondary route/server option.
■
The maximum number of hops, or routers that a packet can cross, is
15, except for NetBIOS packets which can cross no more than
7 routers.
■
Before you define static routes on your system, you must define at
least one IPX interface.
■
Static routes remain in the routing table until you remove them or
until you remove the corresponding interface.
