RIP has problems, but NLSP should be much better. My point is that these mechanisms are not part of IPX, but are the routing protocols that are run in addition. IPX plus RIP is no worse than IP plus RIP, in fact is has better metrics. Nobody would run RIP in a large network, so why do you compare IPX+RIP with IP+some better routing protocol? [remainder of message is about other things than IPX routability] I agree there are problems with IPX and the protocols on top of it, but so are there with IP. For example, the severely limited address space. NFS is not very efficient, and very insecure. Seeing only the disadvantages of IPX and the advantages of IP seems to be very popular. I have done investigation for selection of routers to be used between branch offices (over slow leased lines and ISDN) and I agree IPX and NCP are not optimal. But tests with IP and NFS in the same environment did not come out any better.
