Acknowledgment packet — A compression protocol packet that
acknowledges receipt of an IPX slot initialization packet. The
transmitting node continues to send slot initialization packets until it
receives an acknowledgment packet. After receiving the
acknowledgment packet, the transmitting node begins to send
compressed packets.
IPXCON does not track acknowledgment packets.
IPX Route Aggregation
IPX Route Aggregation enables you to introduce routes learned through RIP
into an NLSP backbone in a summarized form. Route aggregation compactly
describes many IPX network numbers simultaneously by using an address and
mask pair. For example, all addresses from C9000000 to C9FFFFFF can be
represented using the address C9000000 and the mask FF000000.
Figure Figure 5 on page 34 shows a typical topology for using route
aggregation, a backbone network with several RIP areas attached. In
Figure
Figure 5 on page 34 , the information within the backbone is minimized
by having routers R1, R4, R8, and R9 report address summaries for the
attached areas. In this scenario, the default route is the only information about
reachable external addresses that must be transmitted within an attached area.
Therefore, information within the attached areas is minimized.
