Whether to use the IPX Address Mapping Gateway
The IPX Address Mapping Gateway provides the following advantages:
You can connect to a backbone network even when your local
network numbers are not compatible with the backbone addressing
scheme.
If the routing protocol in the backbone does not support route
aggregation, like most implementations of NLSP, the routing
protocol probably cannot manage the number of network addresses
from every user. Even if the routing protocol could handle route
aggregation, network numbers might be assigned in a way that does
not lend itself to aggregation. The IPX Address Mapping Gateway
enables the summarization of routes in a manner transparent to the
routing protocol by mapping many network numbers to a single
number outside the local network.
To use the IPX Address Mapping Gateway, refer to
Address Mapping Gateway” on page 86
.
Whether to use IPX Route Aggregation
IPX Route Aggregation allows your router to compactly report many IPX
networks to a connecting backbone network. IPX Route Aggregation is
most useful when several RIP networks are attached to an NLSP
backbone network. Information in the backbone network is minimized by
having the routers that connect to RIP networks report address summaries
for these networks.

Whether to change how your router propagates type 20 packets
Type 20 is an IPX packet type that refers to any propagated packet.
NetBIOS packets, for example, are type 20 packets. If your router
processes a large number of type 20 packets, you can control how it
propagates these packets through its interfaces. This can reduce the
amount of traffic on a LAN.
