RIP and SAP Aging Timer
These fields allow the user to independently configure the amount of time that RIP and SAP
will keep a RIP Routing Information entry or SAP Service Information entry in their respective
databases if a Broadcast packet has not been received, which indicates that a Route or Service
is still available. The configured values are 4 to 4095 thirty-second intervals, where 6 is the
default value. This value should be two or more times greater than the Broadcast interval to
avoid prematurely Aging an entry, in the event that an IPX router or server is temporarily
unable to send a broadcast packet due to low buffers, or if a broadcast packet gets lost.
RIP and SAP Broadcast Entries
These fields allow the user to independently configure the number of RIP and SAP broadcast
entries which may be included in a broadcast packet. Configurable ranges for RIP are 50 to
133 where 50 is the default. Configurable ranges for SAP are 7 to 16 where 7 is the default.
The number of entries is also subject to limitations based on the configured Packet Size,
defined on the IPX Options panel. Use the following calculations to determine the maximum
number of broadcast entries that may be included in a broadcast packet:

It is recommended that the default values be used, unless all IPX Routers and Servers on the
same network support larger RIP and SAP Broadcast entries. Some older IPX Routers and
Servers do not, and they may discard the packet or not process it completely.
