IPX & TCP/IP??

[rudolphjk]

Do routers route TCP/IP packets, but continue to broadcast IPX down all ports on the router?
What kind of effects on bandwidth does this have, ie if you replace a hub with a switching hub on a network running both TCP/IP & IPX protocols (50% IPX, 50% TCP/IP), how much bandwidth will be saved using a switched hub? And would that savings be propotionate to the number of ports available/used on the hub/switch?

Both IP and IPX are routable protocols, so you CAN have routers for both or a router that does both. It is also possible to get a bridge router (brouter) that routes some protocols and bridges others. so even IPX would be filtered by the bridge if you choose that idea.

Switches operate at layer 2 so they don't care if it is IP, IPX, Appletalk, or DECnet.
Switches can run full duplex and can support n packets at a time on a n port switch, while a hub can support half duplex and one packet at a time, so the larger the switch, the more improvement over a hub of the same size

Can there be any ill-effects from having a mixed-protocol environment?
In particular, there are some PC's on our network that connect to the same server with TCPIP sometimes and IPX at other times. Under novell's properties the default is set to use IP, and IPX alternatively. Does this indicate a problem with IP on the LAN, and if so, what kinds of problems might be they be?
Or another thought...does Novell determine the protocol when the OS is first booted, or for each individual connection to the network the PC may make?

We've been using both and I haven't noticed any problems. As to why some of your PC connect with IP then IPX, I don't know. Maybe collisions???

I have mixed IP, IPX, DECnet, LAT, NetBIOS, and Appletalk networks, it is not a problem as such, but it is easier to manage just one or two protocols. The one thing you can't give for your heart's desire is your heart. - Lois McMaster Bujold
