Example 2

Access points 2 and 4 in Figure 4-3 service IP wireless

stations as well as wired IP and IPX hosts on the secondary

LAN. These access points have an additional requirement

to pass IPX traffic.
The IPX router in this network periodically sends IPX-RIP

(Routing Information Protocol) frames for coordinating with

other routers. These do not need to be forwarded to the

secondary LAN because the secondary LAN does not

contain a router.
To filter the RIP frames, it is necessary to use the

[SubTypes 1] configurations. The example sets filters for

three different cases: DIX, 802.2, or 802.3 SNAP frames.

In many actual networks, only one of these would be

required, since all stations would be configured for one of

the three options.
