These are what makes Novell a “chatty” network. Remember these SAP packets act like little children demanding attention: “Here I am! Here I am! Here I am!” Get it? Good. Supplemental Lab or Challenge Activity: 1. Try adding Novell-ether as an encapsulation. Do you have to add it for every interface or is it on <strong>by</strong> default? 2. Add in a third router and keep the IPX party going! 3. Try switching the mask to 20 bits. What changes have to be made in your planning? Ok…now go do it! So What Have I Learned Here? In this lab you learned how to implement dynamic IPX routing along with dynamic IP routing. We just did this to make things easier even though it sounds complicated. There is not much IPX left in the “real world…” In some schools, some banks, and some companies but it seems to being dying out. Too bad…its really nice…it’s even similar to IPv6…coincidence? I think not. Guest Router Name Steve Gibson runs a nice security website: http://www.grc.com His site will scan your system (free) and tell you of any security leaks or potential port problems. His site says they will not keep any information. Heck, it’s a good start any many of my security colleagues frequently use the site. 329
Basic IP/IPX with Static Routing Objective: To learn how to set up basic IP/IPX between two routers on a network using static routing. Tools and Materials: (2) PC/workstations (3) Routers (2) Switches (4) Straight-through cables (2) DCE/DTE serial cable (2) rollover cables IP Lab Diagram: e0 st con s0 s1 con st e0 NIC st ro ro st COM1 COM1 NIC Workstation “A” Workstation “B” IP Addressing: Routers Hostnames Steve Gibson E0 192.168.1.1/24 192.168.3.1/24 S0 192.168.2.1/24 (DCE) n/a S1 n/a 192.168.2.2/24 (DTE) Workstations A B IP 192.168.1.2 192.168.3.2 SM 255.255.255.0 255.255.255.0 GW 192.168.1.1 192.168.3.1 Step-By-Step Instructions: 1.
