Lab #4 AnswersNET 413Page 3 Lab4/NET413-Lab4-Assignment.docx NET 413 Lab #4 – Static Routing Lab ASSIGNMENT DOCUMENT Due Monday November 8th, 2021 by 11:59 pm This lab can be done either on an equipment pod in the Network Security Lab (CDM 348) or it can be done using Packet Tracer starting with file NET413-Lab4.pkt. There is a separate Lab #4 Answers document that accompanies this assignment. You should type all answers into the Answers document and submit it according to instructions. BEFORE you start configuring any equipment you should do the following: 1. Read this Assignment Document completely. Examine and understand the network diagram. 2. Type information about your subnets into Table #1a: IPv4 Subnets and Table #1b: IPv6 Subnets in Part 1 of your Answers document. 3. Based on IP Address Requirements section below, choose IP addresses and type these into Table #2a and Table #2b. 4. Based on Routing Requirements section below, determine what static routes must be set up on which routers, Enter one line of information into Table #3a: IPv4 Static Route Plan for each IPv4 static route that you will configure. Enter one line of information into Table #3b: IPv6 Static Route Plan for each IPv6 static route that you will configure. If you want me to check your values in Tables #1, #2, and #3, you can send them to me by e-mail and I will check them within 24 hours. Using Tables #1, #2 and #3, follow Implementation steps to configure devices, test connectivity, and then copy and paste screenshots into your Answers document as specified in Part 4 of that document. Lab #4 – The Lathcore Sales Network The Lathcore Sales Network Lathcore Corp. has Sales offices at three sites: Los Angeles (LA), Chicago (CHGO) and Washington, DC (DC). Lathcore has dozens of PCs and servers at each site, though we only have one Sales PC at each site in our test network. Lathcore has completed IPv6 upgrades on all devices on their Chicago and DC sites, which are now dual-stack (support both IPv4 and IPv6). However, the LA site is still IPv4-only. The LA site network administrator refuses to even allow you to enable IPv6 on the LA router (so don’t do that). Your job is to design, configure and test a set of static routes that allow any PC or Switch at any Lathcore site to ping to any PC or Switch at any other site using the shortest path with the fewest hops. Lathcore executive management also insists that you configure and test floating static routes that maintain network connectivity if S-Link 1 (between LA and Chicago) goes down, because they’re using a low-cost carrier service for S-Link 1, so this link is not expected to be very reliable. IP Addresses and Student Numbers (
) Each student should substitute Student Number (SN) with any number between (10 and 50). Any place that you see “” in an IP address, you should substitute your Student Number. For example, looking at the DC-PC addresses on the Lathcore network diagram - if my Student Number were 11, then my DC-PC IPv4 and IPv6 addresses would be 48.11.2.10 and 2001:11:93:2::10, respectively. IPv4 Addressing Requirements The IPv4 Subnet IDs are: · LA-Sales: 48..1.0/24 · DC-Sales: 48..2.0/24 · CHGO-Sales: 48..3.0/24 · S-Link 1: 100.0..0/30 · S-Link 2: 100.0..4/30 · S-Link 3: 100.0..8/30 IPv4 Addressing requirements: a) Each of the 3 S-Link subnets contains two assignable IPv4 addresses. The DCE interface must be assigned the higher IP in its subnet. b) The Fa0/0 interface on each router (LA, DC, CHGO) must be assigned the first assignable IP in its IPv4 subnet. c) The VLAN1 SVI on each switch (LA-SW, DC-SW, CHGO-SW) must be assigned the second assignable IP in its IPv4 subnet. d) Each PC (LA-PC, DC-PC, CHGO-PC) must be assigned Host ID 10 in its subnet. IPv6 Addressing Requirements The Subnet IDs for each IPv6 Subnet are: · LA-Sales: 2001:48::1::/64 · DC-Sales: 2001:48::2::/64 · CHGO-Sales:2001:48::3::/64 · S-Link 2: 2001:48:EE::/126 IPv6 Addressing requirements: a) On S-Link 2, the CHGO end must be assigned 2001:48:EE::1 and the DC end must be assigned 2001:48:EE::2. b) The Fa0/0 interface on each router (LA, DC, CHGO) must be assigned the first assignable IPv6 address in its IPv6 subnet. c) DC-PC and CHGO-PC must each be assigned Interface ID = 10 in its subnet. Routing Requirements A. Required IPv4 Pings: IPv4 pings and traceroutes from any PC or Switch to any other PC or Switch on any other site must be successful. Each router must be able to successfully forward IPv4 packets to any of the three IPv4 Sales subnets. B. Required IPv6 Pings: IPv6 pings and traceroutes from CHGO-PC to DC-PC must be successful. The CHGO and DC routers must be able to successfully forward IPv6 packets to either of the two IPv6 Sales subnets. C. Shortest Path Routes: When all links are up, each packet
