Yeah, a legacy protocol question. I can answer those! &;-)
IPX does fast switching by default. You can limit the number of entries
stored in the IPX route cache to free up router memory and aid router
processing with the "ipx route-cache max-size" command. To further improve
performance, you can also configure the router to invalidate fast-switch
cache entries that are inactive with the "ipx route-cache
inactivity-timeout" command.
Cisco IOS software also supports IPX Multilayer Switching (MLS). For more
information on IPX MLS, refer to the "Multilayer Switching" chapter of the
Cisco IOS Switching Services Configuration Guide:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/switch_c/xcprt5/xcdmsipx.htm
There are a bunch of optimization features. Cisco has done a terrific job
dealing with Novell bizarreness for many years.
To reduce routing and SAP traffic, you could use:
* Enhanced IGRP for IPX instead of IPX RIP
* NLSP instead of IPX RIP
* Static routes instead of IPX RIP
* Snapshot routing
* SAP filters
To reduce traffic across a WAN, you could use
* IPX compression
* IPXWAN
* SPX spoofing whereby a local router sends SPX client/server keepalives
instead of requiring keepalives to traverse a WAN
* watchdog spoofing whereby a local router sends NCP client/server
keepalives instead of requiring keepalives to traverse a WAN
* IPX access lists
So, the real question is, of course, what problem are you trying to solve?
Hope this gives you some ideas, though.
